Breeding Birds

If you have a House Wren or Gray Catbird singing in your yard, or hear a Wood Thrush caroling while you walk the Henson Trail, it’s a good bet there’s a nest nearby! First Fotos and Early Birds 042Avian migrants have passed through Montgomery County, so the birds who wake us up with their sunrise songs are species that breed here. This is the season of the Breeding Bird Survey. The BBS is a roadside bird count, an annual trek with stops every half-mile (totaling 50 stops) to listen, look, and note all birds seen and heard in exactly three minutes.

I participated in the survey as a volunteer counter for 20 years. Every spring, I spent a June morning recording birds at all my stops. My route, which crossed Montgomery County from east to west, was one of the original ones laid out in Maryland by the Patuxent Wildlife Research Center in 1966. Scientists analyze the collected data to establish trends in bird status and develop conservation priorities.

Many changes were obvious over the years. The major one was development, of course. I grumbled, “I used to get Eastern Meadowlarks and Field Sparrows at this stop and now the fields hold town houses.” Traffic got worse, its noise masking birdsong. Lou, who was driving for me, now was tasked by the scientists to count all the vehicles that passed us.

More of us participate in citizen science with bird, butterfly, and amphibian counts, or monitor water quality, and we set aside land to be protected habitat. Even small neighborhood parks are benefiting. Long may American Goldfinches harvest seeds in our back yard and Wood Thrushes sing beside the Henson Trail!
