Purple Martin Update (2009)

It's been a terrific spring for my purple martins. The colony has doubled each year since I started three years ago and this year is no different. There are 13 pairs nesting this year - compared to 6 pairs last year.

My current setup will hold a total of 16 nest, 12 in the house and 4 in the artificial gourds. With 13 nest taken this spring, that leaves just 3 available nesting spots. I think it's time to add a new duplex next spring!

Okay, lets take a quick peak inside;

For those unfamiliar, purple martins nest together in groups called colonies. In fact, they are completely dependant on man-made nest houses in the eastern half of the United States. Purple martin houses must be specifically designed for their needs and must be mounted in an open space where they hunt for flying insects.

Just for fun I made my own nesting record chart using Microsoft PowerPoint. This chart shows which nesting areas have eggs, which ones have chicks, and the ones that are empty. The X and the number beside it represents the number of chicks in the nest. I update the chart each time I do a nest check - usually once a week until the chicks begin to fledge. Click to enlarge.

6-3-09 Nest Check

As you can see I have a total of 30 eggs remaining and a total of 34 hatched chicks. That's a lot of babies!

Excellent & informative post Alan. We don't have any similar species over here nesting in that format.

Les said...

I bought my parents a Martin house as they certainly need it on the Eastern Shore (mosquito heaven). Unfortunately the Starlings moved in and will not move out.

Darla said...

We have several Purple Martin Condos in our neighborhood. We love to see them flying around eating the mosquitos! How in the world did you get up there to take those photos...ladder?

Janet said...

That is impressive Alan. How do you get up there to count the eggs and babies? Doesn't it disturb the birds?

Snap said...

Aw they grow up so fast, next thing you know they will be flying out of the nest.

I think you are a wonderfully benevolent landlord to provide so much free high rise accomodatin and keep tabs on the welfare of your tenants.
Terrific home invasin photos.

Great post Alan. Looks like the hotel business for purple martins is booming.

Why is it that they they are dependant on man-made nest houses in east USA? Did something happen to their natuaral habitat there?

mick said...

Great photos - especially the ones inside the nests. Nice to be able to see all those details from eggs to babies - and eventually fledglings.

Wren said...

Incredible pictures, Alan. I have been tempted to get some of the plastic gourds, but until this year I hadn't seen any martins around the other houses in our neighborhood.

I hope you'll continue the chronicle until the babies fledge.

dAwN said...

Great information!those bear chested chicks are adorable!

Denise said...

Very cool, just love what you've done for these Martins and I enjoyed learning about them. Great photos, thank you.

Aeka said...

wow..Great photos and good post.!

DK Miller said...

That is so cool.

susan said...

Les, Make sure you use Starling Resistant Entrance Holes (SREH)Then no more starlings!
Darla, those house can be lowered. SOme have telescopic poles and others are on a pulley or even a winch!
Janet, No, it doesn't bother them at all. Check out My Purple Martin Blog when you get a chance!
Gwendolen, The native Americans have been putting up gourds for them for so long that the purple martins "forgot" how to find a natural cavity to nest in. Isn't that interesting??
