Counting Winter Birds: A Pre-Christmas Bird Count
Led by our member and Brookline Bird Club's statistician, Bob Stymeist
(right side of photo), this group of birders circled the pond
and kept a record of the numbers of each species that we saw or heard.
Indoors at the end, after we made a record of our sightings, Bob did
a counting estimation exercise with us, using beans to represent birds.
