I'd like to echo Chris' comments and pleas for birders to concentrate on a
specific
area over the long term. We see many of the same things that Chris is reporting
and
can add very early appearances of northern species like Yellow-bellied
Flycatcher.
We start fall banding around 4 July for this very reason. By now, species like
Yellow Warbler are well into migration while others are in a large area
dispersal
phase. There is so much to learn and, as a group, we know relatively little
about
the timing and routing of dispersal and migration.
We've been doing daily point counts here, in addition to banding, for 25 years
now.
The effects of warming and the result of the conversion from small dairy to
factory
farming with the loss of pasture and concomitant changes in field crop
practices, as
well as the elimination of hedgerows, has decimated many local breeding
populations
and flat out extirpated others. We'd never have a handle on any of this without
the
daily data.
Thanks to Chris and others who take on this relevant way of birding.
John
