jaegers - not easy

We're in the midst of an unusual appearance of pelagic birds into Long
Island Sound, something that any birder with an interest in such things
knows and has probably checked out or would like to check out for
themselves. Most recently this has resulted in a flurry of  jaeger reports,
both from boats and from shore, primarily from Hammonasset.

It's good to bear a couple things in mind. First jaegers are well-known as
one of the most difficult groups of birds to identify. Second, we're now in
the time period when Long-tailed Jaegers migrate through the Northeast and
Great Lakes. CT's three documented records of the species range from Aug 28
to Sep 3 (although one is hurricane related).

While jaegers are never routine within Long Island Sound, Parasitic is the
species recorded most often (by far) and the one being reported over the
past few days. It's tempting to just default to Parasitic if you see a
distant jaeger (especially if you'd really like to get one at species level
on some sort of list), but the reality is that really distant jaegers
probably warrant only "jaeger sp."

Certainly any attempt to ID a Long-tailed Jaeger will require strong
documentation, probably with multiple photos for anything less than an
adult. But we'll never get the documentation if everyone just defaults to
Parasitic for listing reasons.
