Calling all bird watchers!! This weekend is the Great Backyard Bird Count.

12/07/2025

These feathers, found out on Greenbury Point on Thanksgiving weekend, belonged to a Redshoulder Hawk. Based on the large number of feathers, some with evidence of blood splatter, this bird fell victim to predation. The likely culprit is a Great Horned Owl, known to prey upon smaller raptors. Great Horned Owls have been documented on Greenbury Point in the past few years.

It's a great weekend to take a walk at Greenbury Point Conservation Area to see what the late autumn leaf drop has revealed. A common sight are the little leafy nests perched high in the trees built by our native Gray Squirrels. These bundles are called dreys and are a cozy shelter for the squirrels as the weather turns frigid. Here is an excerpt from a Washington Post article explaining more about their construction.

'Dreys are marvels of engineering. There are three layers. The outermost layer is made of leaves and twigs. Next is a tightly woven layer of bark and vines that provides some insulation. And inside that is the soft center where the squirrels snuggle. It is composed of “fluffy stuff,” John said: everything from shredded paper to bedding pulled from old couches left on the curb. ...

'Related females will nest in groups. “You can have three generations of females nesting together,” John said. “During the day, they’re all spread out doing their own thing. During the evening is when the really interesting stuff happens.”

The squirrels come home. Males disperse when they’re grown, but when it’s very cold they are sometimes given sanctuary in the drey of an unrelated female. On especially frigid nights, as many as eight or nine squirrels will nest together.'

Yay! It's Bat Week! Greenbury Point does host a population of bats. Let's appreciate them! ❤️🦇

❤️🦇It's Bat Appreciation Week!🦇❤️

Take a moment to appreciate that our native bat population is one of our best defenses against mosquitoes and other insect pests.

Just one Little Brown Bat can munch up to 1000 mosquitoes a night, and that number quadruples for nursing mom bats! 🦇= 🚫 🦟

Maryland has 10 species of bats, all in the microchiroptera group. These are small, insect-eating bats. These bats work for YOU!! So let's hear it for our Maryland bats, heroes of the night! ❤️🦇
