[margin]Thoughts on
Migration[/margin]

3. That in spring the individuals which breed with
us are the first to arrive, the more northern breeders
arriving later and those going furthest north closing
the spring flight of each species.
Evidence - F'axon & I have both watched certain individuals
which were among the first of their kind to arrive
and which from some peculiarity of note or coloring
or from marked attachment to a certain locality
were easily recognizable and in repeated instances,
we have found that those early arrivals remained
to breed at or near the place where they were
first seen.

4. That in most if not all genera of land birds
the species which breed furthest south are the
first, and those which go furthest north the last,
to arrive in spring. This rule is subject to but few
exceptions. It is especially satisfactory in respect to
the Thrushers, Warblers and Sparrows. (e.g. Turdus fuscescens
I. [?]; [?] Motacilla vs. S. [?] & many others)

[delete]5. That in autumn the species which breed only to 
furthest north reach of Mass. pass us on the southward migration later
than species of the same genus which breed
further south[/delete]
