I am not a university trained ornithologist but especially given warming and its effect on weather patterns that the migratory months would not be the time to assess numbers rather breeding season.
Regarding that and comments all this year on "quietness" in habitats during breeding season (again I am not a trained ornithologist) could it be that the steadily decreasing numbers of birds and decreasing density in appropriate habitat is leading to a decrease in song due to decrease in territorial encounters.
I say this because I live in a clearing in the woods which is marginal habitat for catbird and song sparrow. I have a difficult time telling each year if they are there in breeding season or not. My casual observation is that they don't sing much. Because there are no adjacent territories of their species?

I think back to this spring. Up here in the mountains it was definitely off. They came, then departed. It was strangely quiet. Usually by late April the ruby-crowned kinglets are screaming bloody murder. But this spring it was quiet.--
This month, most birds had moved thru, and it was quiet. Then last week we had a wave and it was very busy. I heard from friends that even Florida was off this spring.,

It seems to me that the unusually fair weather we've experienced for the past month or so might be playing some role, at least, in why we are seeing fewer birds. We've had no fallout-producing conditions, so we're not seeing huge numbers of downed birds. I'm not so naive as to think that there are as many birds in existence as there were 20, 30, or 40 years ago. But they aren't suddenly all *gone*. Observations like those in Cape May prove that that is just not the case. Rather than be alarmist about a seemingly quiet migration season, perhaps we should be thankful that the birds have had such good flying weather in recent weeks? What we observers are calling a "bad" migration season might actually be quite successful for the birds themselves--a fallout, while fun for birders, can be devastating for the birds involved.

otherwise TamaracCherryfield, as much as possibleJoel WilcoxI hope it's not all over yet. At least there was a report from Cape May 2-3 weeks ago of a carefully-estimated 56,000 warblers in one day.Down here in south FL (back at work) warbler numbers so far are maybe a bit down from normal, but not much.

Maybe most of the birds are gone, it almost seems obvious. Certainly compared to 30 - 40 years ago.--

Thank you BAB for weighing in. Sorry to hear your migration was a bust down your way. If your and my experience is representative it is odd isn't it? In past low years the theory I heard floated is that for some reason birds shunned the coast in favor of an interior, mountain ridge on ramp to the Atlantic Flyway. But, I never drilled down to test the voracity of this. Another theory I hear is that rather than "Big Days" birds are trickling through in smaller flights. But what I am seeing looks more like no migration rather than a trickle migration.
Bye,
Richard
