Re: [Maine-birds] Re: Baltimore orioles

To gauge the number of orioles breeding in Maine, the best source would the compilations of the annual Breeding Bird Survey.  There are several BBS routes in Maine, and the results of these would show a decline if one exists.  Seeing large quantities of orioles, or lack of same, during migration isn't an indication of relative abundance.  That said, I have noticed a decline in this species in Beautiful Downtown Nobleboro as well.  Ten years ago we would have two pairs singing and visiting oranges.  This year we didn't put any oranges out because I haven't heard one singing.

One must remember orioles winter in Central America, a rather small area which has had some significant changes in land use in the last 50 or 60 years.  If you're looking for reasons for a general decline, this would be the place to start.

Phippsburg status of Baltimore Orioles
Four years ago, I took photos of 18 of them in one tree at my next door neighbors. Along with them were 25 Rose-breasted Grossbeaks. It was astounding. Never has that
