Boston Peregrine Falcon- Nictitating Membrane

On June 16th, the Boston Peregrine Falcon (the remaining male of the Christian Science falcon pair) stopped by our office's window ledge. I assume this is the male of the pair because he is so much smaller than the female that we were used to. Another noticeable trait is how big the male falcon's feet are. Just look at the size of those talons!

You can see the falcon's nictitating membrane up on its right eye. I'm not sure the reason for this, perhaps his eye suffered an injury or infection and he was keeping it up to protect it. At least twice I saw him lower it to look directly at us but he then he put it immediately back up. Does anyone know a lot about nictitating membranes? They've always fascinated me in birds. Here's one of a red-tailed hawk nictitating membrane that came up when it was preening/scratching.

In one of these photos you can see part of the falcon's ID band. It looks like it has the letter I and the number 7 on it.

Thanks David- I'm glad you found my blog. Mostly these falcons prey on smaller birds. I see the evidence on our window ledge (wings and feathers).

Oh-those are great! We have falcons in Portland-I'm going to make more of an effort to get close-up photos of them next year.

Well, Here We Are — Back to Birding Girl After 11 Years

Well, here we are—after an epic 11-year hiatus, I’m sitting back at my Adirondack chair, overlooking the picturesque cranberry bogs we live on now. I've swapped my super strong coffee for a hoppy, locally-brewed IPA to celebrate the end of the work day, and starting work again on my personal project- BirdingGirl. Honestly, it feels a little surreal. If you’re popping in and thinking, “Wait, she’s posting again?”—yep, it’s me! The binoculars are still close by, the dog is snoozing nearby, and yes, the birds have kept me company all along. Life Lately: Birding (Mostly) at Home Let’s get this out of the way—I never stopped birding. Not for a minute! Sure, life looks a bit different now. Marriage and kids will do that to you, right? These days, “getting out in the field” means looking up at the trees lining the trails leading to the cranberry bogs I walk my dog on, listening for great-horned owls and wood thrushes, or watching a flash of yellow as the warblers return each spring. I ...

Difference Between Grackles and Starlings

I saw a sad sight today during my lunchtime jog—a dead grackle. Or was it a starling? I'll get to that in a minute. I was making my way down to the trail along the Charles River when I saw what I thought was an injured bird in the middle of the road. It was just sitting there and I figured it was just stunned or maybe had an injured wing. The bird probably didn't have much of a chance, but the least I could move it out of the road. As I got closer to the bird I saw it had its mouth open and then I realized the gruesome truth—it was dead and was frozen in that position. I just got shivers thinking about it. The poor thing. Anyway, so it got me to thinking 'What is the difference between grackles and starlings?' I use the two interchangeably and haven't really made an effort to sort it out. Until now. I like to use All About Birds from the Cornell Lab of Ornithology as an online resource. The site is comprehensive and easy to use. (I also really like the 'Cool ...

Using Birds to Control Tomato Hornworms

Here's a lovely macro shot of a tomato hornworm caterpillar taking a little break from gorging himself on my tomatoes. Ever seen one before? They're huge and pretty startling to come across when you're pruning your tomato plants. They blend right in, until you accidentally touch one- hopefully not with the horned end! This picture was taken near the end of the season so I wasn't SO upset, but I definitely want to prevent hornworms for next season. I started doing some research on how to get rid of tomato hornworms and the good news is you don't need to use insecticides or crazy home remedies- birds will do the work for you! This great website I found- the Yardener has a whole section about insect pests in the vegetable garden. According to the site, feeding birds year-round will help you control the tomato hornworm problem in your garden. For bird lovers, this shouldn't be a chore at all. Just keep your feeders full with desirable seed like black-oil sunflower s...
