Trumpeter Swans are an increasingly familiar sight in western, central, and
to some extent northern New York State, especially in the winter when
parties of birds move down from Ontario in search of open water. Evidence
suggests that the bulk of the NY population is derived one way or the other
from the reintroduction program in Ontario. This ambitious project is based
at Wye Marsh in Midland ON, which is near the southeastern corner of Georgia
Bay on Lake Huron. Ontario raised swans have stayed to nest at a few spots
within NYS and their offspring have spread further afield. Many of the
Ontario birds are wing tagged (yellow with a unique three letter/number
code) so their movements and survival can be easily tracked. There are other
reintroduction programs (e.g. Ohio) but we await solid proof that any of
their birds have reached into NYS. Unfortunately, few of the birds hatched
in NYS have been marked and we have little information on their survival,
movements or ability to nest successfully.

Trumpeter Swan have remained very scarce in the eastern and southeastern
portions of the state but this seems to be changing. On Monday, Bob Wilson
found a wing-tagged Trumpeter Swan (number 'A60') at Agawam Lake in
Southampton, Suffolk County. This is 28 miles from Yaphank, also in Suffolk
Co, where two untagged Trumpeters have returned for another winter.
According to Harry Lumsden of the Ontario Trumpeter Swan Restoration
Program, 'A60' is a female that was hatched in 2009 by two tagged swans (981
and E51). She was banded at Hillsburg ON (northwest of the Lake Ontario
shoreline) on 7 Oct 2009 and then resighted at several location within
southeastern Ontario during the following winter, spring and summer. In July
of this year, A60 was found injured in Rosemount ON, taken into rehab and
then released a short while later near Mansfield ON. There have been no
additional reports of this bird until now. Are A60 and the Yaphank pair
harbingers of changes to come? I would imagine the milder marine climate and
less extensive snowcover of Long Island might offer an attractive and
reliable wintering ground for these long-lived birds. Time will tell.

NYSARC is actively monitoring the status of Trumpeter Swan in anticipation
of adding the species to the official New York State Checklist. Guidelines
have been established to help decide when a species can be considered
self-sustaining (remember the fate of Eurasian Skylark and European
Goldfinch) and in the Committee's opinion this has not been met quite yet.
Monitoring the movements of identifiable individuals such as A60 is
extremely useful in this process and NYSARC encourages submissions of marked
birds or birds from areas where Trumpeter Swans remain very rare.
