Afternoon Storms and Brutal Heat

Wednesday, June 9th, 2010

With the heat index in the 100’s the fierce thunderstorms are ALMOST welcome. I say almost because with each of these storms severe winds of upwards of 45 MPH that would last past sunset, have inflicted some damage.

The nest of mockingbirds right outside our garage was blown down and the 2 partially feathered nestlings had perished. The large Sabal Palms lost a few fronds and the seed pods that the mockingbirds had made their nest in was woefully inadequate for the punishing winds.

The purple martins hung on to their perches well into the night seemingly afraid to detach themselves. I suspect an attempt to find protection within their nests would have had them blown away at some point during the storm. Fortunately the storm died down and all seemed quite but the previous week had these storms coming in almost on a daily schedule.

The winds were no problem for the martin poles. So other than the mockingbird casualties, all is well. Unfortunately the same can not be said for the laptop which ran the colony cam, so no live web cam at the moment. A new laptop is on the want list…any one???

2009 Going Out as Purple Martins Come Home!

Wednesday, December 30th, 2009

Scout reports are popping up on the west and also the east coast of Florida as the last few days of 2009 brings in the first of the purple martins for the 2010 season. As I read M.Dingman’s report of a ASY male purple martin singing over his empty backyard, I was reminded as I have reminded others via Twitter to get your housing up early. I will be working on my housing this weekend and heading my own advice, but one never knows how early the martins will come.

As of today there have been 6 reported purple martins returning home. All 6 in Florida from Naples to Punta Gorda, from Melbourne to Okeechobee (which is a stones throw from myself) So, the reality that I may be caught with my “houses down” is a real possibility. This also means that the live Birdcam will be going up very soon.

So get them houses and gourd racks up!!

In closing I want to thank all of you for continuing to follow this blog and reading about my colony. I hope 2010 brings you peace, prosperity and many many martins!

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.

The Davie Roost has MOVED!

Sunday, June 21st, 2009

Apparently the raccoon predation was just too much for the purple martins at the Davie Road Racetrac gas station. They are no longer roosting at that site. I went on Friday night and the few purple martins that flew over head, never came down to the trees. The dead martins on the ground were still there, but no fresh kills. Apparently the roost was abandoned shortly after my visit on Saturday June 13.

Fortunately for all us purple martin lovers, a fellow PMCA forumite “Stingray” was shopping in the area and happened upon the new roost location. It is now located at the “Tower Shops” just South of 595 on the East side of University Drive, in the same plaza as Home Depot. The chances of finding the new roost location is almost a miracle in my book and the disappointment I felt this Friday is now replaced with excitement again. woo hoo! I can’t wait to go and see the new spot. I hope the folks at the Tower Shops greet the purple martins with the same welcome attitude that they enjoyed at Racetrac Gas station. The potential for a negative response is high considering there is no overhead cover to protect any shoppers from the rain of bird poop that they will be experiencing.

I have been ridiculously busy trying to prepare an article for you on emergency care of purple martins…I should say, first responder care of purple martins. I went to Folke Peterson Wildlife Center on Friday and met another one of their wonderful Veterinary Technicians, Faith, who let me photograph the HY purple martin while he was force fed. He is still not accepting food from the hemostats and his outlook is poor. Other than the fact that he is being force fed three times a day and can not fly, he appears calm and comfortable. A perfect gentleman.

Other interesting finds at the Wildlife Center was a Chimney Swift nestling that was brought in recently. Eyes shut and chattering loudly, the little nestling looked so out of place in his box. My heart bleeds for this little guy. For great information on Chimney Swifts and what you can do to help these birds visit ChimneySwift.org  I was shocked to find out that contrary to what I had read on the swifts breeding range, South Florida, the West Palm area to be exact, has a nice little colony of swifts that live out my way. I am eager to convince my husband of the need to put up a Chimney Swift tower! I am so excited for this project for next year. Can you imagine THAT on a webcam?

Another interesting patient at Folke Peterson was a juvenile NightHawk. Which is quite the coincidence considering that I recently wrote a blog entry about these illusive birds that I NEVER thought I would see so close. Like a pet rock, it sat in its cage with its big eyes staring back at me. A curious bird and not very bird looking at all, up close. Faith told me of the odds against rehabilitating this bird and all birds that are strict aerial insectivores. A diet that is never fully able to be replicated, humans can only come up with a fair approximation of the dietary needs of such birds. I hope this one makes it too.

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.

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

Where is the Rain?

Tuesday, May 12th, 2009

2 days of pregnant clouds and not a drop of water. The neighborhood ponds are drying up and the wetlands at some of the areas of Grassy Waters Preserve look more like scrub land than swamp. For hours the sky was black and thunder could be heard in the distance. The clouds swirled but not a drop fell here.

 It seems like there has been a bustle of morning hour activity at the purple martin housing ever since the babies have started fledging last week. I am not sure if some of the activity is from other area colonies or my own purple martins. They swoop in with zest and proceed to make themselves quite the nuisance. Peeking in compartments, being scolded fiercely by protective parents, vocal and joyful in both song and flight they are everything that is fun to watch about purple martins. Though a bit mischievous, I have witnessed no serious fighting.

The nestlings on the nestcamare big and ready to go at any time. They are busy flapping about in the gourd, stretching and preening their new flight feathers. Preparing themselves for a maiden flight. There is always at least one with its head looking out the front of the gourd and the others stuck inside looking about or napping. Today they are 26 days old and they are officially old enough to fledge at any moment. The mother comes to the opening and perches for some time often bringing no food, which signals that they are indeed ready. The parents will decrease feeding as fledging approaches. This technique serves 2 purposes. First, it decreases the attractiveness of the nest with its “room service” so that the babies will want to come out to feed. Secondly, to decrease their weight which can be more than an adults. Talk about baby fat! Try getting airborne with all that extra weight though.

 I am still postponing nestchecks on this rack due to the amount of babies ready to fledge and I have been unable to do a nestcheck on the other 2 units due to the thunder.

European Starling fledglings have come around, chaperoned by an adult. One was as close as a foot from the repeating S&S nestbox trap but never landed on the trap itself. Of course I was seriously disappointed and it reminded me that I must go back to Green Cay Nature Center to further observe the gourd rack there. My terrible luck with trapping this year along with the population explosion locally, has brought me to a new level of sadness for our native birds.

What’s Up?

Wednesday, May 6th, 2009

The purple martin nestlings are beginning to fledge in the numbered gourd rack and I have suspended nest checks on that rack until probably Saturday. Come Monday there will be another 4 nests getting close to fledging, that I will again suspend nest checks. All this to avoid the dreaded premature fledge. I will do a partial check tomorrow on the house and the lettered gourd rack and I will try to move the camera so that you can see a new vantage point of the colony.

As my nests get ready to fledge this also means that the colony will get a lot busier with visiting martins from the surrounding area coming over for a visit. It should be fun to watch as the youngsters, still unsure with their landing technique try to land on the housing. It’s always worth a laugh. It also means that the time is drawing closer for the birds to begin gathering at their premigratory roosts. But I won’t let myself think of that. There are still plenty of babies yet to fledge.

For local readers of my blog, I hope I see you on Friday and Saturday at Folke Peterson Wildlife Center for their “Rescue Fest”. The center is trying to raise funds in this challenging economic times and is having a grand shindig for the family. Friday they will be having a silent auction, live music, comedians and Saturday will be the fun stuff for kids. All proceeds directly benefit the center and the animals that they care for. I will be giving a presentation on Purple Martins on Saturday at 1:00PM and hope to meet some of you in person.

Last Check for a While

Saturday, May 2nd, 2009

I did the last nest check yesterday that will be done for a while on the gourd rack that is on the birdcam/colonycam. The nestlings in gourd #9 are now 28 days old and they are looking like they could go at any time.  To prevent premature fledging after I lowered the rack (oh so quietly) I placed a sock in the gourd opening. I had tied a string to the sock so after the check was doen and the gourd rack raised up, I could gently pull on the string to remove the sock. All went well on the check and the babies looked wonderful. No bugs, fat and lean with hints of blue showing on their fresh new feathers. The next time I see them, in early 2010, they will be sun-bleached brown.  

There are at least 5 nests that seem to be abandoned. There are 3 scenarios I believe could be at play for this situation. It could be a case of egg dumping or it could be young inexperienced SY’s playing house or lastly, drought affecting food supply thus reducing clutch rates. Whatever the case may be, I have come to terms with my goal of reaching the magical 100 mark having to wait till next year.bottom view of S&K guard

No more snake attacks and the bird/snake netting along with the spray foam in the holes of the S&K predator pole guard will let me sleep at night. In the picture you can see the white dried foam coming out of the holes in the guard that allowed the snake to pass through. The foam is commonly found in hardware stores and a common brand name is “Great Stuff insulating foam sealant” or “Handi-foam”. It actually comes in handy for several things and I have heard of some folks using it to modify cheap plastic purple martin houses to increase the insulation and help keep internal temps comfortable. One thing I should mention to those considering an inexpensive purple martin house. Consider the amount of effort you will put into the house modifying it and the life expectancy of the house itself. If you expect to get more than a handful of seasons out of the house you may very well be overly optimistic. Sun and UV rays can change plastic and you may notice discoloration or loss of opacity and brittleness. Though some may disagree, more light means more heat and it is generally agreed upon that darker is better, when it comes to the interior of a purple martin house. The plastic can always be painted with a product like Fusion paint for plastic but again, now you are adding your time and money into the upkeep. My point? Always consider these factors when deciding what kind of Purple Martin house you want to buy. Want to read more about deciding on a purple martin house?

Ratatouille?

Friday, April 17th, 2009

 When I received an email from Tim M. regarding the large rat looking object on gourd #11, I had to admit it looked odd. For the people who look in on my colony, to see the large black ‘thing’ clinging to the side of the gourd, I apologize if I frightened any of you. It does look like a rat hanging on the side but alas it is just a few socks with rocks inside. The added weight of the web camera housing had the gourd leaning over to the side. Not that the Purple Martins minded this at all. BUT the eggs and now nestlings, kept settling just below camera view. Every time I did a nest check I had to move the nest over so that the nestcamcaught a better view of the action. I had tried multiple times to adjust the camera, to no avail. Finally, at my wits end, I zip tied the rocks as a counter weight the gourd. With one egg left in the gourd I hope to catch a better view of the babies now that they are being fed.

 I am not sure about the remaining egg on the nestcam. Whether or not it will eventually hatch. I had counted 4 eggs multiple times on previous nest checks. And though it is probably a case of me missing the 5th egg (several times) it could also be an egg that it was dumped by another female. Well, it could happen. Though eggs can hatch up to 48 hours apart, the window is closing fast and if the egg has not hatched by the morning, I am afraid its chances are slim. Mom and dad are busy feeding the 4 nestlings, so incubation of the final egg is dwindling. After the pipping egg death, I am hesitant to handle the egg. If it is still unhatched in another day I will look at it closer.

The male ASY martin is being very enthusiastic about feeding his nestlings. I watched him bring in a small dragonfly that appeared way to large for the little nestling and try for some time to stuff it down one of the babies. The little nestling had wings sticking out of his mouth and I watched as he was apparently trying to pull the wings off of it. It was comical but this sort of thing can be dangerous.
