I opened the top of the tank and was greeted by an unusual sight: Instead of perching on a branch or standing on the ground, these guys were vertically clutching on to fabric that had been placed along the left side of the tank wall. Their chirps swelled to a crazy cacophony and their mouths opened as they vied for position when I came at them with their soaked science diet cat food on my fake mother's beak -- the kind of scissor handled tweezers I've mentioned in previous posts.
These little guys are the color they are to obviously blend in with their environment of choice... the smoky ash-encrusted inside of your chimney. They obviously breed at a time of year when there are no fires burning, and this explains why they grip upright. Yes, they make some noise but they are there for such a short time. And they do you the favor of catching thousands of pesky-to-humans insects.
They used to build in hollow trees but they now choose chimneys due to loss of habitat... and with all the new gas fireplaces, that alternative is also dwindling. If you have any in your chimney, please think twice before you hire someone to shoo them out. They usually just remove the nests and discard these helpless babies! Oh no, that just won't do!
If you click HERE, you can read more about that. Among other useful info it says: "Chimney Swifts are protected by Federal Law under the Migratory Bird Treaty Act." and if you hire a company to clean your chimney, you need to find a reputable company whose policy it is to protect the little dears.
I am very curious to know if any of you have ever had or seen them before.
