I look at Long Point Bird Observatory from this Canadian site 
https://www.bsc-eoc.org/birdmon/default/popindices.jsp  This banding site seems 
to have the longest record. They report a population index which I presume 
accounts for banding hours. If you look at the different species, it seems that 
most of our forest dwelling species are doing well especially warblers. This is 
probably related to the maturation of our woodlands since 1960. These increases 
come at a time when we supposedly lost a large amount of tropical wintering 
habitat. It also is time period of more cell towers and now wind farms. This 
data only goes to 2015. It doesn't account for the last few seasons. Personally 
I haven't noticed much declines in fact, veeries, rose-breasted grosbeaks, 
ovenbirds, blackburnian warblers, chestnut-sided warblers, least flycatcher 
among a few others seem up to me this year in the areas I go in June. I have 
noticed a dearth of wood thrushes. American Robins don't seem as common either 
in my neighborhood. Probably all local variations at least here....

Not at all in banding reports which show lower numbers on average in some 
places, more in others and a healthy bunch of birds. Uniform agreement that 
weather caused a strange migration with both flyovers and late, if much at all, 
movers after a blocking front(s). All of this is localized and some happened 
around here las year as well whereas other areas are just fine. The mix of 
species here as I mentioned, tends to agree with that idea. Even here, some 
areas are reporting normal species and numbers. I doubt the disease theory as 
there is no evidence. The weather mortality reports are minimal and confined to 
birds landing in awkward place like parking lots. I have only looked at 
Saw-whet breeding and it appears its cyclic self and very dependent on prey 
populations.

I remember this conversation last year. If there is a marked rapid decline in 
song birds as reported, then something has occurred in the past couple years 
that is wiping our birds out. Habitat loss is a gradual slow process that would 
not be so readily noticed on a wide scale from year to year. The weather 
patterns, I don't believe were bad enough for massive mortality events 
(although I haven't looked into this in full depth). Wind farms keep popping 
up, but again its a gradual pressure that wouldn't manifest itself in 1-2 years 
for such reported rapid declines. The only thing I can think of is if there is 
a disease (west nile?) that is affecting songbirds and other species? This 
could explain two poor breeding seasons. Does anyone know if this is being 
reported in species of songbirds???

The current "record" based on banded birds returned to the wild is 8 years 2 
months. That said, Nancy may well have been enjoying the progeny of that first 
pair as their site fidelity is high.

Likely "your" pewee was at least two different birds, as their lifespan is ~7

It really is an odd summer!  We also are missing "our" peewee, who has been 
here reliably for the 14 years I have lived in this house. Missing him!There 
are at least 2 pair of great crested flycatchers and on Friday an Indigo 
bunting showed up and is still around singing his head off from the tops of the 
black locust trees.There are sapsucker babies (that sound like they are humming 
in morse code from inside the tree) and bluebirds too.  So down one peewee, up 
a bunting? Guess I would call that OK....but I want my peewee back. thanks for

Hi!

Over 30years of banding, migration and population study here and we experienced 
and ever increasing paucity of birds. About 15 years ago I wrote a report 
citing these losses. While many can be linked to loss of habitat mainly due to 
factory farming, that didn't account for the lack of song. We prognosticated at 
the time that populations within species were undergoing a drastic 
diminishment.That has since been shown to be even worse than we guessed ( based 
on American Bird Conservancy data sets).

A result most noticeable was in song. With fewer competitors, birds in lesser 
numbers arrive on native land and , if they find it still existent, establish a 
territory. With little or no competition, the territorial song is short lived 
-after all, why expend energy needlessly? Defense of territory is seldom needed 
so in season song is greatly diminished.

That doesn't mean it stops entirely but certainly far less than what we new 50, 
40 or 30 years ago.

Fast forward to the crazy migration we experienced this spring. Expected 
species have still not checked in and we guess they either overflew or were 
content to our south. We have the same experience with Veery here and Wood 
Thrush has been declining steadily. Least Flycatcher, Warbling Vireo are all 
missing and the fancy Thrushes once a stopover certainty haven't been seen for 
several years. Yesterday, we finally had a single Pewee. On the positive side 
we are inundated with Grosbeaks, Purple Finch, Great-crested Flycatchers, 
cuckoos and others that are normally here in much smaller numbers.

Looking South to the greater DC area, many of these species are still there and 
that's abnormal. Check the ADK reports and they are also having a strange year 
although I've not seen any thoughts on the subject from that area.

The short answer is an unusual migration window with lots of weather effect, 
rapidly declining populations creating an environment where our old 
expectations are no longer valid.

I liked it much better several decades ago. We have stopped banding passerines 
and happy we did as the disappointment would be even greater.

Best,

John

I have noticed, as have others, that the woods have not been as plentiful with 
bird song as normal.  On my recent walks at Upper Buttermilk I have been very 
disappointed in the total absence of Wood Thrush, Veery, and Scarlet Tanager.  
By this time in past years I've always have several of these birds.  On my most 
recent walk (Friday) I was wonderfully surprised to hear 2 Wood Thrush and 2-3 
each of Veery and Scarlet Tanager.  Why the sudden "reappearance"??  I know I'm 
going to be criticized for asking, but could some birds (species) still be 
migrating in?  If not, then why did they finally "show up"?  Some could argue 
they were busy with nesting.  But I've never experienced birds remaining 
completely mum during the nesting season.  Another argument could be that they 
are now moving around after the first brood.  I doubt that would explain the 
numbers of these species I had all of a sudden plopping down in Upper 
Buttermilk?  By the way, we picnicked at Upper Treman yesterday and bird song 
was relatively infrequent.  Do any of you have any thoughts on this subject??
