The November Cayuga Bird Club meeting will be this coming Monday, November 14
at 7:30 pm at the Ornithology Lab. Cookies & conversation begins at 7:15.
Our speaker, Vanya Rohwer, curator of the Bird and Mammal collection at
the Cornell University Museum of Vertebrates, will give his presentation - "Of
Mansions and Shacks: Understanding Divergent Nest Building Behaviors Between
Two Populations of Yellow Warblers". .Yellow Warblers have one of the widest
breeding distributions of all North American wood warblers, ranging from the
equator to Alaska. Different breeding sites pose different challenges to
successfully raising young, and one way for Yellow Warblers to overcome these
challenges is by building nests that are well suited to local environments.
Vanya Rohwer will discuss why Yellow Warblers breeding between two different
locations in Canada a temperate and subarctic site build such dramatically
different nests, and will highlight some of the process of discovery associated
with this research.
For his work on Yellow Warbler nest morphologies, Vanya traveled to Churchill,
Manitoba where Polar Bears loomed in willow thickets, Beluga Whales breached in
Hudson Bay, mosquitoes buzzed insistently, and the dusk twilight of northern
latitudes lingered till 2am. Members are invited to dinner with Vanya before
the meeting at Aladdins in Collegetown at 5:30. Please RSVP by noon Monday to
cl...@juno.com so reservations can be made.
