In recent years, beavers have taken up residence in Sapsucker Woods Sanctuary, home to the Cornell Lab of Ornithology in Ithaca, New York. Beaver activity on Sapsucker Woods Pond has caused some problems, so we turned to Beaver Solutions LLC to help us tackle the issue. The device installed in the pond will allow us to coexist peacefully with the beavers!

Wood Ducks are small and stocky ducks with a crested appearance and a relatively long tail. Males are ornately patterned with iridescent colors and intricate plumage details. This species prefers tree-lined ponds and swampy woods, and is one of the few duck species to nest in tree cavities or even nest boxes placed along the edges of ponds.
By the early 20th century, the beautiful Wood Duck had been nearly driven to extinction by overhunting and habitat destruction. But in 1934, an innovative federal plan (the Duck Stamp Act), brought together hunters, artists, and wildlife managers in a conservation partnership, and now the Wood Duck and other waterfowl have made a huge comeback. Read the full story of one of the most successful but underappreciated conservation successes of the last century.

Blue Jays cooperatively harass two American Kestrels who are perched in a large dead tree in Sapsucker Pond. One of the Kestrels may be a parent and the other a juvenile. The Blue Jays continued the mobbing behavior for approximately 15 minutes, diving and following the Kestrels.
