This year’s annual Winter Census on the Lumberton campus on January 23 was cold, but relatively productive, recording 47 species and 5,166 individuals.

The 2022 Medford Campus Winter census was held on January 15. On that day, the temperature barely reached 25° F by noon; twenty-three species were recorded with a total of 850 individuals.

Twelve of the 13 nest boxes with metal poles and predator guards successfully fledged young with no predation. Several boxes had more than one successful nest. The bluebird success rate (#young fledged/#eggs) increased from 23.3% in 2020 to 85.7% in 2021. Tree Swallows and House Wrens also had significant improvement in 2021.

There are many nesting boxes at Lumberton Leas. While they all could accommodate bluebirds, most of the poles were wood (which black snakes and raccoons can climb) with no predator guard. In an effort to reduce predation, 12 of the original boxes on wooden poles have been replaced with boxes on metal poles with predator guards.

The ML Birders conducted their annual winter census on 01/23/2021 for the Medford Campus . The weather was very cold and windy with brilliant sunshine. The only modification we had to make to the old adage of “no such thing as bad weather only bad clothing” was the addition of the socially responsible mask.

The ML Birders conducted their annual winter census on 01/15/2021 for the Lumberton Campus. The weather was hazy sun with temperature in the low to mid 40’s.

Cold to be sure (13° when we started), but with virtually no wind, it was a nice walk through the trails and around the perimeter path. Monarch Lake was partly frozen and hosted thousands of geese.

While the first hour was slow, by about 9 AM a mixed flock of Robins, Juncos, and white-throats with a few Myrtles, woodpeckers, and a Sapsucker were feeding actively in the hollies and evergreens.

Censusing started at 8 AM with a temperature of 16 degrees but little to no wind except in the open areas by the creek. Still waters were frozen, and the creek was mostly frozen after a week of cold weather.
