I like to record the departure dates for the local migrants such as the
cuckoos, Dollarbirds, Sacred Kingfishers etc. as it is interesting and
important information in light of global warming. I have had more
overwintering (or late departure and early returning) Rufous Fantails in the
Clarence Valley, North Coast New South Wales, in recent years. Is this a
response to global warming?
There is one complication that I only considered recently. Departure dates
are not necessarily departure dates for the local population but may reflect
the last date that birds from further south move through a particular area.
Local birds may have migrated weeks earlier.
