Quality, not quantity.
The 80th Boonton Christmas Bird Count was conducted on Sunday, December 27, 2015. The recent mild weather continued with the temperature ranging from 45 F degrees at dawn to 60 F degrees at 3:30 PM. Midnight to early morning was damp. A dense fog enveloped the count region until a south wind kicked up at 9:00 AM clearing out the moist air. The sky was overcast for the entire day. No freezing has occurred all season; all water was open.
The highlight of the count day was a new species for the count, Painted Bunting (PABU), which was cooperative at Hatfield Swamp in West Caldwell, Essex County. The PABU is present since December 18 when it was found by David Blinder, who also located it yesterday for the CBC along with Chris Thomas.
Another excellent find was a Lincoln’s Sparrow near the south end of Troy Meadows, found by Jeff Ellerbusch and Roger Johnson.
Along with the above mentioned highlights and other results on the positive side of the ledger, this year’s Boonton CBC as a heavy list of missed and nearly missed species.
With all parties reporting, the total count of species is 85 and 5 count-week species. This represents the lowest number of species since 82 were recorded in 1989 – twenty-six years ago.
All the records mentioned below are kept in the same stream, rather than separating the highs from the lows.

- 20 Northern Shovelers is the 3rd highest total in the 21st century (115 in 2001; 40 in 2011).
- 83 Green-winged Teal is more than double the 21st century average of 39.4.
