Runt Update- A Visit to Busch Wildlife Sanctuary

Saturday, July 11th, 2009

After a long evening of re-hydrating the purple martin nestling and then this morning continued Gatorade and crickets, the nestlings belly was much softer, poops were normal and most importantly-he was still alive.

All morning without any chirps, I was wondering if mom was anywhere around. Usually you would think that the nestling would give out a few chirps if he heard her. I did see a SY female coming to the porch twice in a 4 hour period. Once to drop off a large cicada on the outside porch. I wasn’t impressed with her efforts. At around noon I lowered the gourd rack and took out the 2 thin-est of the remaining 4. I left the 2 strongest nestlings which after careful aging, I determined them to be 22 days old. The runt definitely is feathered, for the most part, like a 16 day old. The 3 skinny ones then made a 20 minute ride to Busch Wildlife Sanctuary in Jupiter after having a drink of gatorade.

I met David Hitzig, the executive director of the facility. It was great to finally visit this center that I had heard about but never visited. As you may know from previous posts, I had always used Folke Peterson, which is only a few minutes away, but now that they are closing (due to financial problems) this was a wonderful opportunity to make the drive. Had I known what a full service, top notch facility it is, I would have come sooner. I brought the family and my 2 boys were kept happy and amazed at the animals including Florida Panthers, Deer, foxes, birds of prey and every sort of native Florida wildlife. I meanwhile spoke with David.

He is astute and quite aware of the dilemma these birds find themselves in. Being so late in the season, and no other nests that could foster them, the best place for them is with momma. As negligent as she is, their best hope is to fledge with her. Without the post fledging care that they will receive, their chances are dismal and I know it. My fear is that the runt will be so malnourished, that he would die or be so far behind in growth that he would be left behind or easy pickings for a predator. David saw to it that the birds received a fluid injection to hydrate them quickly. They also got a big meal of juicy live crickets and meal worms before I took them home. Now that the runts belly was softer and poop was normal, I feel much more comfortable returning him to the nest with a day of rescue feedings under his belt.

The 3 were very active on the drive home and after a quick stop at the pet store to by a dozen live crickets, I gave them one last drink of Gatorade and belly full of food. I lowered the rack and placed them back in the nest after checking the 2 much heavier nestlings.

I did see the mom flying about and I think I know what is going on. Before returning the nestlings I heard her calling out to the nestlings with her chew chew call. A call I hear the parents make when they are trying to coax them out of the nests to fledge. That would explain her leaving the food on the outside porch. She is trying to lure them out so they will fledge. Unfortunately she is inexperienced and like most birds, has no access to a calendar. She has no idea that feathered as they are the birds are just not ready to fledge. The runt is so under feathered that it would perish for sure if it didn’t die from the malnourishment first.

The nestcam is now on gourd #6 and my eye is fixed on the action.

Many thanks to Mr. David Hirtzig and to Busch Wildlife Sanctuary. I will be sending in a donation to this fine facility and coming back again soon.

FREE Purple Martin Bird House Plans

Wednesday, July 8th, 2009

Call me a collector but I seem to be collecting quite a number of free purple martin house plans. Thanks to dedicated purple martin landlords such as John Balga and Bob n Jo, and thanks to the Pennsylvania Game Commission, I have put together a small collection of houses that the DIY can build. I even have plans for a gourd rack!

Of course, I am not the handy type so I have NOT made these houses myself. I guess that is why I started PurpleMartins-R-Us. If you are like me and can’t build a birdhouse yourself, check out this large selection of houses and supplies that utilize the latest in purple martin research and innovation. Believe it or not, I did NOT start this business to get rich. I did it so that I can do what I love. If I get rich that is nice but looking at my books, that won’t happen anytime in my lifetime.

So where can you get these plans? Go to the Free plans page HERE and enjoy!

If you know of any other FREE house plans for purple martin houses, please let me know. And please let me know how the house you build turns out. I would love to see it.

P.S. Tonight is the first night that all the fledglings have not returned at night to sleep in the Nestcam! Only one in there tonight. My season is winding down.

Roost Makes News

Sunday, July 5th, 2009

The Broward edition of the Miami Herald ran the story on the Davie roost today. You can read the article HERE.

We drove down to the roost and did not see any martins but we were a tad early so it is hard to say if the roost has, in fact disbanded. It is just about time for the birds to move out but I can not say for sure. My 2 kids were quite tired and I could not bare to have them sit in the car for another 30 minutes to see if the martins would show up. I will have to depend on any of you that may life closer to update me and the blog as to the roosts status.

The story was very nice and a special thank you to the journalist, Julie Levin, who was so patient waiting to see “my” purple martins. Remember, there are photos of the roost at my photo gallery and there is also a video of the roost that is quite nice.

The babies on the nestcam have officially all fledged and the gourd was empty for most of the day. They are sleeping in the gourd tonight though. Looking so big and grown up. Thankfully all the babies appear nice, fat and healthy. Unlike some issues that seem to be going on up North our temperatures, though hot are not too bad and the rain is enough to cool things down plus keep the bugs abundant.

Purple Martin Emergencies-New ONLINE info source!

Many northern landlords are having serious issues with very abnormal low temps and landlords are reporting nest failures and dead babies by the dozens. Early jumpers due to the extreme heat in Texas has been reported and supplemental feedings can save lives. For those with babies that need care, our parent site, www.PurpleMartins-R-Us.com has a page dedicated to Emergencies INCLUDING how to give food and fluids to purple martins, contact info for Wildlife Rehabilitators and more. Feel free to check this information out.

Purple Martin: CSI

Sunday, May 31st, 2009

I have prided myself in the attention I give my birds. Yes, I know, the Purple Martins are not truly mine but the care I lavish on them is appreciated by them. The trust they show me as I hoist the gourd racks up or down and they sit and wait patiently with bugs in their mouths. Waiting to take them into their gourds to feed hungry nestlings. Imagine my chagrin when over the past week or so an ASY male is dive bombing my head relentlessly. Within inches he strafes my head to the point where I fear for my life…or at least my eyesight. Going to the mailbox which is at the opposite side of a acre + lot even rankles him. What could have upset him so much to the point of this hatred he apparently has for me? Forever the OCD’er that I am, I have thought of a few scenarios.

First, I think this male may be the same male from the natural gourd that was eaten by the red corn snake several weeks ago. There are 2 new nests with nestlings that hatched in the last week and the male may well be one of those daddy’s. Could the ASY male that lost his family just be blaming me for his misfortune? The male survived that attack and definitely saw me removing both the snake and the one last remaining dead nestling from that gourd. Could he be associating the tragedy with me as I was the last one seen at the scene of the crime?

Perhaps it is a totally different male from one of the other new nests. There is a new nest of 5 eggs that on the last nest check (May 28) I found one of the eggs had been broken. Could have been the work of a clumsy fledgling. They seem to be going in and out of nest indiscriminately and getting their tails beat in the process. Maybe the male saw me remove this broken egg from the nest? I have heard that one should shield any dead young and/or eggs from the sight of other martins so to not upset them. Though I generally try to do this, there are times when I am sure some birds may see what is going on.

In short, I am not sure what to do other than wear protective head gear and eyewear whenever I am outside. Though I doubt there is any available treatment for my wounded pride.
Nestcam update. The 5 nestlings on the Nestcam are due to fledge as early as June 2. You can watch them leave gourd #4 on the Colonycam. After they fledge I will move the camera to a gourd on the lettered rack and at that time I may move the main Colonycam so that the Sunset Inn house and lettered rack are in view.


Nestcheck for 5/28

Young in nests remaining:  46

Eggs in nests remaining:   27

Total fledged to date:  66

Stormy Weather

Friday, May 22nd, 2009

The pregnant clouds finally broke their water and the rain has been relentless for the last 3 days. 5 minutes of sunshine then another “contraction” in the form of thunderstorms. I am glad and the birds seem to be handling the frequent downpours well. There is enough pause between and the storms are scattered enough that they are feeding just fine. A nest check is overdue on all racks and if the thunder stays away while the kids are napping, I may try to squeeze one in today.

The earliest of fledglings seem to still be returning to the gourds at night to sleep but it is hard to determine just what is going on. The other night on the nest cam I noticed what seemed to be 3 adults in with the 5 nestlings in Gourd #4. They were all sleeping peacefully but I doubt that was the case when the party crasher arrived.

Fledged!

Saturday, May 16th, 2009

Purple Martins on Nestcam gourd #11 have fledged!

It is official, they are flying around like maniacs. A bit unsteady but apparently without incident. The Nestcam was so dirty that it was hard to make out who was even in the gourd. I finally brought myself to lower the rack and in doing so flushed out a few straggler fledglings from gourds #11 and 12 but it had to be done. At approx 31 days old, I knew they would be fine. The Nestcam is now cleaned off and on gourd #4 which needs a watchful eye as I have not seen daddy helping and mom seems to be taking her time with feedings. The babies did not seem as plump as I would like and they seemed a bit bony so I will be watching this gourd closely to make sure that they are getting enough to eat.

Two of the nests are down right nasty and if it were not for a clutch of new eggs in gourd #8 (a renest attempt) I would have done a nest change. This was the first nest check for the numbered gourd rack in over a week so a complete check was long overdue. But to do a full nest check and then do a nest change also would take too much time. The nastiest of the nests is due to fledge within a week so I am considering leaving it be. OR I may go out tomorrow and bring the rack down and change the nesting material. I hate the thought of them in that mess.

Under the lettered gourd rack, I found a dead nestling. Approx 4 days old and it had been dead quite some time. It came from gourd H and the other 5 nestlings in the gourd seemed fine. The are about 8 days old. I will never know what was the cause. An SY male perhaps or just a case of natural death and the parents cleaning house. 

I am unable to check the telescopic pole as the nestlings in the aluminum Sunset Inn house are ready to fledge at any time.

In other news: There is lots of racoon feces on our patio and I am starting to get more nervous. A flicker has been cleaning out the screech Owl box since the owls are gone and one of the tidbits it threw out was a whole owl egg. I fear the owls did not have a successful clutch in my yard.

Partial nest check results (unable to check telescopic pole)

Total Eggs:  17 + (10 eggs unable to verify if hatched)

Total Young:  53 (Plus 15 on other pole?) 68

Total (active) Nests:  22

Fledged to Date: 28

Random Thoughts and an Update

Thursday, April 16th, 2009

I was just outside letting my dog out for his last foray of the night. The air is perfectly comfortable and a perfect South Florida night. The neighborhood Chucks Will-widow is calling out in its haunting and beautiful call. My son who was up all night with a 103 fever seems back on the mend. All is right with the world. 

Friday I will be doing a nest check. Looking at my watch I see it IS Friday so this is not much of a heads up. Since several nests are due to hatch, I will probably do another check come Sunday. (Just for fun!) Sometime between 3pm and 5pm EST, the usual time.  Of course, you can watch me on the Birdcam and laugh at me, if you like.  Also, the nestcam has one egg hatched so far and 4 more eggs at any moment.

Their are several starlings that are regularly feeding in my yard every morning. I have made feeble attempts with my pellet gun, to no avail. My aim is ridiculously bad and every time I squeeze off a shot, I blush with shame. Both from my bad aim and the picture I make, out in the yard in my bathrobe, morning hair and a pellet gun. The neighbors at least have free entertainment. I even have put out my home made wire bait trap which I used last season as a holding cage for the starlings. It is even more poorly made than my repeating nest trap. The starlings have no interest however in the popcorn and cereal I have placed inside. I will persist though. Should I ever manage to catch something with the trap, my husband owes me a sushi dinner. Yesterday evening I saw a lone starling perched on the phone line stalking my colony. Fortunately I am using SREH (starling resistant entrance holes) so my birds are safe, for the most part.

On another bird note. The mocking bird fledgling is almost indistinguishable from its parents. It follows its parents in the yard. Silently doing their wing displays as they scurry from spot to spot on the lawn. I only see the one fledgling which speaks volumes on the survival rate of these brush nesting birds. The neighbors which have at least 2 cats are constantly on the prowl. My dog has chased them out of my yard and away from the purple martin poles on numerous occasions. I am not sure how I will address the issue come fledge time but if I have to chase cats, I will. Another reason to call me a crazy bird lady. All I need now is a little more gray hair.

Pipping Egg Passes Away

Tuesday, April 14th, 2009

Today brought some much needed rain and another nest check. The South Florida drought is again becoming more threatening, but today’s passing showers brought a brief respite. The birds enjoyed the morning shower, though brief, with zealous preening and a social hour. The skies cleared for the early afternoon only to darken again around 5pm and then finally open up for another soaking before dusk. The skies remained solemn as darkness fell and the birds retired quietly for the night.

The nest check started around 4:30 on the gourd rack and house that is off camera. My 2 young children were taking a nap (YEAH!) and I was in checking on them frequently. I finally got to the gourd rack on the webcam right around 5 and the wind was starting to gust.

As I now have 31 compartments, I will post total numbers unless something of interest needs to be posted.

Total eggs: 65 Total young: 13

The two nests in the aluminum house have 6 eggs and 5 eggs, Numbered rack has only one troyer with no eggs. I added 2 more Troyers to the Lettered gourd rack and all the other gourds seem to be occupied but the egg laying has slowed to a crawl. Of the 10 gourds on this rack only 2 have eggs and only 1 egg in one and 2 in the other. I wonder if the dry weather is a form of natural birth control for the martins?

The pipping egg, that I had posted about recently had been in gourd #3. Among the first of this years babies to hatch, these nestlings are between 5 and 6 days old. I counted and there were only 4 of them. I was excited to meet the little nestling that would be some 2 days younger than his nest mates. I was curious to see how he would be fairing as the ‘runt of the litter’. I lifted a few of the fat little bodies out of the way and found the egg buried underneath them. The same as I had left it, with the hopeful hole pecked perfectly in the center of the egg. A small beak just below…only dead. Oh how sad. How close this baby had been to the world. What could have happened? I am guilt stricken.

This brings up an important point about pipping eggs that some may not be aware of.

There are 3 things that can cause a pipped egg to die without hatching.

  1. Humidity too high
  2. Humidity too low
  3. Poor or bad circulation of air

When an egg is pipping the amount of humidity or moisture in the air is critical. Being a wild bird, the humidity level in the nest is not something that we can monitor or adjust for. The birds know what they are doing. Some people have said that perhaps that is why green leaves are brought into the nest. It is one of those things that God endows his creatures with an inner knowledge that man, in all our sophistication, may never truly understand. When it comes to poultry, it is commonly understood that slightly too high humidity can drown a nestling. And humidity just a tad too low can cause the membranes to stick around the nose and basically suffocate the nestling.

The third and last cause, improper or poor air flow/circulation may well have been the likely culprit in this case. Nestlings can pip fast or slow and they do it in their own time. When it comes to poultry a chick can take an hour or a day…it’s really up to the bird. So the fact that I did not see movement was not a concern but, It may well have been dead when I found it initially. We also have to consider that the other nestlings were being fed. The nestlings at 2 days old were already more than twice the size of the egg. They were mobile and wiggling around the nest to some extent. Raising their heads and instinctively positioning themselves in the nest. All it would have taken is one of the nestlings to rest its head over the small hole or for the moving babies to cause the egg to roll over enough to suffocate the nestling inside. I took care when putting the egg back in the nest to position it as I had found it…pip up and small side down. But I should have looked at the egg more carefully, to in fact confirm movement. I should not have assumed that the nestling was alive and well. Maybe in placing it back in the nest after picking up and replacing nest mates, that its ideal spot was disturbed and it was then more likely to roll to the side-sealing its fate? I will never know. Fortunately the 4 other nestlings are fat and oblivious to their brother (or sisters) demise. It’s a hard life-a birds life. Maybe that is why we work so hard to make the little parts we can easier for our martins. As you can see by the post mortem photo, that the nestling appears asleep and peaceful. Its little beak was through the inner membranes.

Speaking of hatching. The eggs in gourd #11 are due to hatch as of Wednesday April 15. So keep an eye out for more pipping and cross your fingers! Watch them on ournestcam, of course.

Other good news is the gourd on the Shepard’s hook now has 5 eggs. I wonder how those babies will feel about me mowing the grass and peeking in as I drive by?

For a grand total of 69 eggs and 10 young.


The Hawk

purplemartin attacking hawkAs usual, the red tailed hawk continues to make lazy attempts at catching one of the martins. I am not very good at raptor ID, so for all I know, it is a immature hawk practicing. The attacks always frighten and always send the martins up in a flurry of purple. He sat on the top of the purple martins favorite slash pine and was punished for his impudence! Martin after martin dove and harassed till he eventually flew off in disgust. He almost seemed embarrassed. Unfortunately, I am sure he will recover and visit again. Come fledge time, I am already making plans to sit out on a lawn chair and babysit. For today perhaps the hawks are busy chasing down mockingbird fledglings that keep finding their way into our garage…much to the chagrin of their parents.


The Surprise

close up eggI had a series of firsts for today. I witnessed my first pipping egg, which is simply put, an egg in the process of hatching. It is pretty amazing and very slow. The nestlings little beak is just visible through the small hole that it has pecked through the shell. The nestling will have to slowly chip at the egg, the entire circumference of the egg. Since this is the last egg in this nest, there is no danger of the shell becoming encapsulated. An encapsulated egg can cause the death of the nestling inside and should be watched for. During nest checks if portions of the shell remain in the nest, you should remove the pieces. These egg shells can fall over unhatched eggs and trap the nestlings inside-encapsulating them within.

My other first was 2 eggs discovered on a Shepard’s hook gourd. The first year I put up housing for purple martins, the first birds that landed on it were Tree Swallows. Now at the time, I did not know that the Tree swallows were only migrating through, as south Florida is a bit too far south for them. I put up the shepards hook as a “just in case”. I placed it about 35 feet from the purple martin housing and every year I get a male who claims it. Last year a pair built a nest but no eggs were ever laid in it. I think it was just an extra nest built by a pair that nested in one of the other gourds. This year appears to be different. I checked the shepards hook, more as a courtesy, not really expecting to find anything, and lo and behold!!! 2 shiny white eggs! The Shepard’s hook is not more than 5 feet in total height. It has an aluminum stovepipe predator guard, that I wax every year. And now it has 2 eggs! Time will tell if the eggs will be tended to. Perhaps they were just dumped there. A female needing to lay eggs but not having a mate, nest, or the inclination to tend to them. But there they are. I hope they will be OK. It does go to show how martins will overcome many “imperfect” site issues for the sake of being within the safety of a large colony. As most people will tell you that the ideal height for a purple martin nest is at LEAST 10 feet, 12-15 even better. So a 5 foot Shepard’s hook is a stretch.

As I did todays nest check I looked up at one point and saw well over 45 birds flying about. I was dumb-founded and I must say it was an impressive site. As always, my heart skipped a beat.

I AGAIN tried to adjust the nestcam and can not get it aimed quite right. I will try, yet again on Saturday when I do the next nest check. I hope to go to Green Cay this Friday. I wanted to go last week but between my dental problems and our schedules; it was not possible.  I must admit that my spirits are always lifted when it comes to purple martins, but as of late any joy is somewhat muted with pain. Hopefully the worst is somewhat over and my dental issues will improve, as will my humor.
