chickadees
I participate in Feeder watch and my numbers are consistent over the past few years - 4-6 at feeders at same time.

A fellow teacher told me that she is seeing fewer chickadees than normal.

Has anyone noticed a decline in chickadees?

I've not seen a single chickadee at my feeders today and that is very unusual. Only been one or two recently.

I live in South Salem, NY, just over the state line from Ridgefield. I have been doing Project FeederWatch since the 2007-2008 season. I am down just a little bit this year, when I have been getting 3 birds each count period. Over the years I have averaged 4 birds, with a maximum of 7 one year, with the norm being a max of 5 birds. So, I don't see a whole lot of difference.

I just saw on the NYSbirds-L list that the CBC parties in Central Park saw exactly1 chickadee! I don't know what the norm is, but in the 80s and early 90s I did the Lower Hudson count (of which Central Park is part), and I don't remember anything like that coming from those teams back then.

So, maybe the chickadee numbers are down.

My personal observation concurs with that of others that the BC Chickadee population here is in decline. My lone observation is not useful, but when many observers-and spring census and Christmas bird counts concur (do they?-I don?t know that)-then perhaps we have a trend. If memory serves me correctly (and it often doesn?t), Sylvia Halkin?s speculation is that competition between this species and Tufted Titmouse is a possible mechanism for this population shift.

I also should have mentioned that they saw only one Tufted Titmouse.

This summer my chickadee population in the yard went from multiple visits a 
day by many different chickadees down to zero!   Since the cold weather 
started, I have now one chickadee, maybe two.

From Steve Broker (Cheshire):

I've checked Connecticut CBC statewide data on observed chickadees and titmice for the past 30 years (1983-84 through 2012-13), with the following results:

Total # Black-capped Chickadees = 347,963 (Average = 11,599/year)
Total # Tufted Titmice = 148,084 (Average = 4,936/year)

Average # Black-capped Chickadee in 5-year intervals:
1983-84 through 1987-88:  12,949
1988-89 through 1992-93:  13,375
1993-94 through 1997-98:  13,661
1998-99 through 2002-03:  10,628
2003-04 through 2007-08:  11,078
2008-09 through 2012-13:  7,901

Average # Tufted Titmice in 5-year intervals:
1983-84 through 1987-88:  3,601
1988-89 through 1992-93:  4,408
1993-94 through 1997-98:  5,525
1998-99 through 2002-03:  5,458
2003-04 through 2007-08:  5,862
2008-09 through 2012-13:  4,763

Note:  these are raw numbers, not adjusted for total party hours.  We've had nearly the same number of Christmas Bird Counts (18) taking place during these 30 years, except:  The Napatree CBC has an 11-year history; Edwin Way Teale, Trail Wood has conducted 27 CBCs during this time period; Barkhamsted has had 29 CBCs.

The most recent 5-year interval for numbers of Black-capped Chickadee is 61% of the first 5-year interval.  The first significant drop-off year was 2000-01, and in 10 of the last 11 years B-c Chickadee numbers have been well below the 30-year average.

The 5-year interval 2003-04 through 2007-08 for numbers of Tufted Titmice is 163% the first 5-year interval.  Tufted Titmouse numbers first jumped above 5,000 in 1993-94, and they have remained so for all but 4 subsequent CBC years.  Interestingly, Tufted Titmouse has seen an overall decline in numbers, on average, during the last 5 years.

I believe Connecticut Christmas Bird Count numbers for the last three decades support the view that Black-capped Chickadees have declined in early winter numbers during the last 10 years or so, while Tufted Titmouse numbers over the same 30-year time period have increased in corresponding magnitude, although with some indication of more recent leveling off or decline.

I hope to address this issue further in the 2013-2014 Connecticut Christmas Bird Count review article that will appear in an upcoming issue of The Connecticut Warbler.
