The occurrence of Razorbills the past two winter has gotten me
thinking. Although their presence may be good for our lists, it may
be the result of some environmental ill (bad weather, loss of
expected food supply etc. Or, it could be a consequence of success
and they are extending their range.
I think it may be the latter. Razorbills have occurred regularly in
the past. Their numbers have been increasing, just as other fish-
eating species have increased in Long Island Sound. The Razorbill may
just be the next species to make Long Island Sound a regular
destination. Another thing to consider is that seabirds are long
lived, so that once they get into the habit of wintering at a
location they will likely return and lead their offspring here. This
is all speculation, time will tell.
Linsley (1843) recorded it for Stratford,
Merriam 1877 considered it rare in Long Island Sound.
The species was subjected to egg collecting until the migratory bird
treaty in 1919 where it has since recovered.
Over the past 30 years fish eating birds have greatly increased in
Long Island Sound.
Ospreys, Double-crested Cormorants, Herons, Gannets.
Below are the records I have for this species.
What is interesting is that the 1948 record is considered the third.
But, I have yet to find one and two.
