We checked on the Bluebirds last night and they continue to grow. The Tree Swallow nest is on hold. Maybe the cold weather stopped the building for a while.
Meanwhile I'm finding even more bird cams for wasting my time. Cornell University has an amazing Red-Tailed Hawk cam. The clarity is amazing and they provide some great close-ups. There are 2 hatchlings and one mroe int he process of hatching. At the top of the page you will also see a link for their Great Blue Heron nest. It's due to have hatching start in about a week.
