Agreed!<o:p></o:p&g --001a114db6e61b42d305388a4ccf Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable folks, A few related observations from conducting intensive bird surveys in the Fredericton area for the last two weeks. It seems like at least reduced vocalization rates, mixed flock formation and some post-breeding dispersal are occurring. Vocalization rates of nearly all species are now very low other than for a brief period around dawn. However, family groups were prevalent and some mixed-migrant species family groups were forming. Other than at dawn, Alder Flycatchers were only heard calling. Common Yellowthroats and Blue-headed Vireos were abundant and still singing relatively frequently. Least Flycatchers were heard in appropriate habitat only in the first week. No Yellow Warblers and only a couple of American Redstarts were heard in those two weeks. Nashville Warblers were heard in appropriate habitat only in the first week. In terms of Canada Warblers, only about 1/4 of about 40 birds we detected in appropriate habitat were heard vocalizing, and almost all of those detected in the second week were silent. In Alberta at least, upon young fledging, American Redstart family groups quickly move to much more structurally dense habitats, presumably where food is more abundant and/or risk of predation is lower. It appeared that these movements increased in length over time. Eventually these types of local post-fledge movements must translate/grade into more directed, 'migratory' movement...
