This nest photo is from July 23rd, 2019 in Gravenhurst, Ontario.

Nest ID needed

Nest is in evergreen tree (6-7ft high). May be an old one. No eggs.

Banded Carolina Wren and Downy Woodpecker/nest ID needed!

Birding at Edith Moore in Houston, lots of birds including a banded Carolina Wren and a banded Downy Woodpecker. We also came across this nest.

Nest ID please! Suspected hawk nest

The nest is made of sticks and leaves. It’s at least 1 square foot, but possibly a little larger. It’s about 60 feet up but I’m not good with guessing height measurements. It’s towards the top of the tree, in a crotch from the main trunk. I have no idea how old it is, so I’m unsure if there was a body of water nearby when the nest was built. It’s a forest habitat, and a little bit of ways from the nest is an area that floods easily. I’ve seen Red-Shouldered Hawks, Red-Tailed Hawks, and Broad-Winged Hawks in my area. I’m guessing it’s a Red-Shouldered Hawk nest, but a Cooper’s Hawk nest is also pretty likely. Any ID help is appreciated!
