A Murder of Crows

Mr. Cone’s Ornithology Class Observes Crows in Lawrence

This past Tuesday, my 6th period ornithology class took a field trip to Lawrence, where we observed a large flock of crows. Crows flock in hundreds during the winter, which we got to witness firsthand at an industrial building on Merrimack street. Our class was working to answer the question of why these birds gather in such large numbers? After our field trip we were tasked to analyze a few different hypothesis as to why this could be. One hypothesis is that they gather for protection (strength in numbers), while another concludes that they gather because a certain spot is most suitable to their needs, so they all congregate in that one spot.

In order to watch the crows interact we fed them cat chow, which according to Mr. Cone, is one of their favorites. The birds were hesitant at first because we were close but eventually decided the food would be worth it. We were surprised by how little competition existed amongst the birds even with the food present. There was seemingly no squabbling amongst them despite the large number of birds. We were quite fascinated by one of the crows, which only had one leg. We observed that this bird had less power for take off but it’s flying abilities were not impacted. Overall it was a great opportunity to observe the crows first hand and to work on a question that many, many scientists have dealt with.

We ended the night with a quick McDonald’s stop to fuel our brains after our scientific field work. Today, we will head outdoors for on campus exploration of the wide variety of birds that exist on our campus.
