This is in regards to the crows in Ithaca NY, so just over 200 km from Niagara Falls, as the crow flies. <br /><br />"During the summer the two species can be distinguished by their stages of molt. In much of their range American Crows breed a month or more earlier than Fish Crows (Johnston 1961, The biosystematics of American crows, Univ. of Washington Press; Clapp and Banks 1993, Raven 64: 90-98; McGowan 2001, Fish Crow (Corvus ossifragus) in Birds of North America, No. 589). In upstate New York American Crows start incubation the first week of April, while Fish Crows don't start until May. Most birds do not molt until they are finished breeding, and the molting schedules of the two crows reflect the month difference in their breeding schedule. The earliest Ithaca American Crows (non-breeders and those whose nests have failed) will start molting in June and will be finished by the end of September. Ithaca Fish Crows, on the other hand, start molting in late July and don't finish until October."Josh Vandermeulenhttps://www.blogger.com/profile/04796806080056515471noreply@blogger.comtag:blogger.com,1999:blog-8130980035846282323.post-25602413814585523242017-07-23T20:15:06.676-04:002017-07-23T20:15:06.676-04:00American Crows in Newfoundland are currently showi...American Crows in Newfoundland are currently showing large chunks of air in their wings and tail as they are in heavy moult.<br /><br />Nice to hear those calls in the cemetery.
