Census

Weekly, volunteers get together to count the various species of birds found at Great Meadows Concord. The results of the census are shared with other Massachusetts birders via the MassBird list. The results are also entered in the ebird a database of North American bird observations sponsored by the Cornell Lab of Ornithology and the National Audubon Society.

Reading the census reports for a day that I've visited the refuge, I've been impressed about how many more species of birds they see. Curious about the process, I joined Kathy Dia, Will Martens, and Alan Bragg in the parking lot at 6:30AM to get a birder's perspective of Great Meadows and learn some of their secrets of success. David Swain joined us in progress and Clayton Swanson's BBC group also provided some observations.

I am glad they allowed me to tag along. I was amazed at how they are able to identify birds. I learned so much. Probably half of the sightings start with recognizing a birds call. How they are able to hear a Willow Flycatcher while all the Red Winged Blackbirds, Robins, Catbirds, and Goldfinches are calling around the refuge at the same time is amazing. Knowing what they are looking for, they can look in the appropriate area to try to see the bird.

Birds in flight were even more amazing. While I was just starting to notice a bird flying, they would generally sight the bird with their binoculars and identify the bird before it disappeared out of view.

Their identifications helped me put names (and quite a few visuals) with the many calls I hear while walking around. This post is a little light on photos since I spent so much of my time observing, and observing the observers. However, I was able to take a few photos to share. (Note any errors in identification are due to my memory, not their skill!)

I had to take a photo of this Common Whitetail dragonfly as it posed on a rock. Normally, you only see them hiding in plain sight on the crushed gravel path. It was so rare to see one on a natural background that I had to take the shot.
