When do you stop doing nest checks? When the nestlings reach about 23 days old. Some folks say 20 days old, but that seems overly cautious to me. All nest checks are on hold as their are tons of nests ready to fledge any day now. The nests that have fledged (about 8 of them so far) are creating much excitement as they peek into compartments and try to steal food from smaller younger nestlings.

A hawk made a late pass right before dark tonight and I am not sure if he was successful or not. The entire colony flew up in masse and with such an uproar of alarm calls that I am sure some bird was taken. Those early morning and late evening attacks are often quite successful. I will have to stay out later tomorrow and see.

I am not sure when the low hanging gourds are due to fledge soon. It will be interesting to see how the youngsters take to the air without having the advantage of height to get them airborne.

It seems like this is a yearly event. (knock on wood) I hope only once a year is my lot in my landlord life. It could be more, I suppose. It definitely could be worse. So far no lasting effects, other than some worry on my part and some moments of terror on the part of the martins that I had to extricate from the sreh gourds. 2 ASY males, one stuck in the sreh and one within the nest. Gratefully and gently freed. They are so amazing to look at up close.

For those that don’t know, Wing Entrapment is when a purple martin becomes stuck in a SREH. It usually happens when 2 or more martins are fighting over a compartment (nest spot) of any gourd or house with SREH (Starling Resistant Entrance Hole) As one bird tries to leave the nest and is trying to fend off attacks from within the nest from a rival or occupant, the bird gets stuck in the entrance. Basically gets stuck when he turns as he is trying to exit. If not discovered fairly quickly the birds in the nest can die as can the stuck bird. I wonder if vented rooms vs non vented rooms have a better survival time and if the deaths are strictly due to the heat build up in a nest with a plugged entrance? Or is it a dehydration issue? Those that have reported deaths from entrapment usually say that they discovered it either the same day or within a day or two of the event.

You can read about wing entrapment in previous blog posts as well as on our parent website, www.PurpleMartins-R-Us.com. Is wing entrapment a reason to not use SREH? Absolutely not. Wing entrapment remains much less common than the threat of Starlings in an unprotected colony. Of course, you have to weigh the pros and cons in your colony along with your sites individual risk factors for both problems.

I was poking around Twitter last night and came upon a tweet from someone saying that their purple martins had returned and were again starting to build a nest under their eave of the persons home. I had to chuckle since I knew  it was no Purple Martin. As many serious birders will tell you, one of the most important facts in properly identifying a bird is knowing the birds range, behavior and habitat. This person makes a perfect example. Knowing that purple martins do not nest on house eaves makes it easy to correctly I.D this bird as a Barn Swallow. Commonly mistaken by the novice birder, many of the swallow species like Purple Martins, Tree swallows, Barn Swallows can be confusing to some. Add in there Rough Wing Swallows and Violet-Green Swallows and even Bank Swallows, even the experience birders will have to look closely and carefully to distinguish these birds from one another.Heck, I wouldn’t have been able to tell a Rough Wing Swallow from a SY Purple Martin before reading up on it myself.

I found a great little site with some great photo comparisons of these commonly mistaken birds at BirdingIsFun.com which has some great tips to help you quickly tell these apart. As for the person tweeting about the purple martins mud nest under the eave of their home, I don’t think they care. But still it makes me think of how many people are out there convinced they are helping martins who may not be? Every year I hear from well meaning people that place housing and tell me about the bright yellow bills of their purple martins or how their martins will not allow other martins to nest in the house. Inevitably I find out that starlings nesting or Tree Swallows are dominating the house. Not to compare a Starling factory with a pair of Tree Swallows, but both examples show how purple martins can be pushed aside.

I recommend our Purple Martin vs Starling ID page to help those that are new to the world of birding. It is a side by side comparison of Purple Martins and Starlings. Even if you are not new, take a look and be sure…If I had a dollar for every time someone swears they have Martins and come to find out they are not!

Another great resource we recently added to our parent site was the addition of Daniel C. Drew, M.D. page on Tree Swallow/Purple Martin and Bluebird/Purple Martin INTERFERENCE. With his permission we added this page to our site so that new landlords can be more successful in getting purple martins in their Martin housing and Tree Swallows and Bluebirds in their respective housing as well. Though that page is up again, in its original site we both thought that the information contained within it is vital to new landlords that have lots of tree swallows and bluebirds but no luck in attracting Purple Martins to their properly set up site.

So what do you use to put in those martin houses and gourds? Many of the available choices that some folks may use work great, some are a bad idea.

Good

Typically the most commonly used prenest material is Pine Straw. Pine straw is just pine needles. It may differ in length and color depending on what kind of pine tree the needles are from but usually pine needles from Longleaf pine, Slash pine or White pine.

Leaves can also be quite water repellent. It really depends on the leaf. Oak are good. Small and flat they are safe.

Corn Fodder which is dried cut up corn stalks

Bad

Grass clippings are a bad choice. First, the grass absorbs water. This in itself is bad enough but then it can mat down and become compacted to the point where water will not easily penetrate. Making your gourd a pool of death.

cedar shavings, though easy to find at any petstore and quite cheap, are not a good choice. They absorb water and stay wet. If you ever use shavings in a cage for a rabbit or hamster, you know! Though I have used it in a pinch, you should try to avoid it.

The most important thing to remember is that American’s have been altering the nature of purple martins for hundreds or perhaps thousands of years. Since martins have lost the instinct to nest in a natural cavity, we have a responsibility to care for these birds as part of our heritage as American’s…whether Native American, North American or United States of ‘American’.

Finally, the martins are getting down to business. Though they may still be having minor squabbles on who lives where, the bringing in of nest material is a sure sign that nesting, egg laying and an onslaught of ASY purple martins are not to far away.

If you are a new purple martin landlord it is vital to play your purple martin dawnsong. Decoys should be up and though some folks report that the purple martins sometimes seem to attack decoys others don’t mind at all.

If you use artificial (plastic) purple martin gourds it is imperative that you place nesting materiel inside the gourds. The slick plastic can make it virtually impossible for the martin to exit the gourd which will leave them trapped inside. So for safety alone, placing nest materiel in the gourd is an important part of being prepared for the arrival of your martins. Of course an added bonus is that it keeps the gourd warm and ready for them when they arrive after a transcontinental migration. Purple martins won’t bring in nest materiel so they can have a warm comfy place to sleep but I am sure it is a welcome feeling for them when they do return.

Naples has just reported the first SY (subadult) Purple Martin of the season on 2/19 so I predict that nesting will be beginning at anytime, here in Florida.Keep playing that purple martin dawnsong and be ready for more birds, all wannabe landlords. Don’t give up!

The last few nights I have seen birds get turned away as night falls. I can almost swear (if I was the swearing type) that more than 2 birds are going into the same gourds. It seems several pairs are co-habitating at any given time. I have witnessed at least 4 birds enter a gourd last night and tonight, and unless these odd birds out are kicked out of the gourds after I go in, they must have stayed the night. I can assume it is not all to friendly in the gourd as I can see the gourd shaking a bit for a few minutes. I am torn as I consider putting up more housing, but then I remind myself that as many gourds or martin houses I put up, the birds would fill them. And do I really want a super colony? Well, actually that would be cool but between kids and tball and piano lessons and all the other “stuff” I would not be able to do them justice. Basically I wouldn’t be able to watch out for my birds the way I want. So until my kids are a bit older and can help with some of the purple martin things, the colony can stay as it is…well, maybe a few more gourds!

I will have to rededicate myself to trying to recruit others into this hobby that I love so much. I have considered having an “open yard” and invite locals to see my colony but the logistics has me confused. Do I do it now early in the season or wait till babies are being fed, do it in the morning or wait till dusk and watch them gather in their big flock before zooming in for the night? Would I rent a Porto-let or open my house to strangers? hmmmm

The colony activity here in West Palm Beach has certainly kicked up a notch. The male purple martins are even heard singing while still in there gourds. I opened up the other gourd rack and filled them with pine straw. Artificial gourds should be filled with a few handfuls of pine straw to prevent them being unable to exit the slick plastic gourds. Even with the black traction strip in my Troyer Horizontal Gourds, they can be difficult, if not impossible to exit. So make sure you place some nesting material in those gourds. I know “some” ultra conservative birders may scoff at giving purple martins this help. They see it as unnecessary interference. But that thinking is flawed. It has nothing to do with altering nature but more to do with preventing a birds death by our hand.

The Purple Martin colonycam is up and averaging about 90% up-time.

Yes, the Colonycam/webcam is up and is streaming the exterior view of a portion of our colony. I am NOT thrilled with the stream provider and my apologies for the annoying ads that pop up. Believe it or not, PurpleMartins-R-Us.com gets nothing for those ads. If I want to stream the webcam without the ads I have to fork over about $100 a month. So unless I win the lottery, that isn’t going to happen. I am investigating other ways to stream the cam but it’s all a learning process so I beg for your understanding and patience.

We are up to about 5 ASY purple martins here at our colony in Florida. The last few days had some cold temps in the 30′s at night and tonight and tomorrow will have strong rain showers with high winds.

I wanted to re-post one of my favorite posts regarding cold weather and supplemental feedings for those up north that will be getting martins soon. Since flying insects are pretty much dormant when temps dip below 40 degrees having supplemental feeding trays available can be just as welcome to purple martins as birdseed to cardinals.

Enjoy!

Extended Cold Spells TROUBLE for Purple Martins

Though it may make a cute picture, the mix of purple martins and extended adverse weather spells almost certain death for our feathered friends. And by extended weather, we are only talking about 2 days or more. Knowing what you can do will help your colony survive these early spring cold snaps.

Adverse weather, to a purple martin, is 2 or more days of steady rain and/or wind and/or cold temperatures below 40F. Only one of these conditions will make it virtually impossible for a purple martin to find enough food to sustain itself.

Being strict aerial insectivores, purple martins have no recourse when it comes to extended weather issues. They can’t forage for food on the ground and when temperatures dip, flying insects are no where to be found. With our crazy weather patterns we have been having and severe snow storms that have it snowing as far south as Florida, it is important to know what you can do.

So what should you do? ACT FAST! Don’t wait for your birds to be too weak to fly before offering supplemental feeding. Purple martins have to be trained to accept our help as they do not recognize food left out for them. If you wait too long your entire ASY purple martin population can die from starvation in just a few short days.

Supplemental Feeding of Purple Martins 101

Q: What do you feed a purple martins?

A: Crickets are the first choice for beginners. Mealworms or Scrambled Eggs are good once they learn to accept what you offer. But these items must be prepared. Mealworms and crickets (if live) should be frozen -till dead, then thawed thoroughly. They can be soaked in water and drained before feeding. Eggs should be cooked using NO oil or butter of any type.

Q: How do you feed a purple martin?

A: Martins that have never accepted supplemental feedings have to be taught or conditioned to eat food we offer them. After a day or 2 of adverse weather, approach the colony slowly. Use a large plastic spoon and fling a cricket up in the air in the general direction of the martins, up over them…remember you aren’t trying to hit the martins with the food. You want them to see the food flying past them. Continue this for 10 to 15 minutes. Most folks report that by the end of that time one or two birds will try to catch what they see flying by and once one starts, others will follow.

Once they accept food from you, the crickets (mealworms or scrambled eggs) can be placed on an elevated platform feeder and they will eat it off of the platform.
