Yesterday, while working in my garden in downtown Ithaca, I noticed out of the corner of my eye a black bird fly into the Norway Maple. I assumed it was a grackle as they are nesting in the tree (and had a fledgling recently land in the street). A Fed Ex guy stopped last week to relocate it to the grass. Anyway, I then heard a loud scuffle in the tree, looked up, saw a larger-than-grackle sized bird bolt out with something in its mouth. My first thought was, "crow took a chick!" Then about eight grackles chased after the crow scolding it up and over the towering Sugar Maple nearby. I did not have my binoculars, but the object in the crow's mouth appeared to be about walnut-size or avocado-pit-size and black. The object was predominantly round in and ball-shape, but I could kind of make out a large head and tiny body with damp feathers as the chase zipped by me in all of about two seconds before the crow and object were out of my view.
After the excitement, or trauma, depending on your perspective, I guessed it was a Fish Crow on the grounds that 1. they have been the dominant crow call I've heard in my neighborhood this spring 2. it almost passed for a grackle based on size (so smaller than American Crow) 3. I heard a Fish Crow call about thirty minutes later and no American Crows all day. Last year, American Crow was the dominant crow call I heard. I found many things interesting about this observation. 1. It appears there is a colony in this tree, and this is the first time I observed a visible count of what appeared to be an entire colony defense system. There was silence in the tree as the chase ensued. Did any stay behind? This flying after a crow is different than watching a robin or sparrow fly into the tree and just get scolded (not chased)...where I could only hear but not visibly count. 2. The crow flew in as if it "knew" exactly what it wanted, where to go, and how it would leave. The entire theft took about five seconds from start to flight over maple. I've heard it calling all spring from within a block of my house. So it probably has been "watching" grackles to figure out where it nests....a bit creepy. Yes, so intelligent, as we know!!! 3. I usually hear the Fish Crows dominate about five blocks in another direction, and have never seen grackles nest in my yard. So I think this explains why a bird would want to change nest locations every year. And has anyone ever speculated why the Osprey at the inlet at the Newman Golf Course stopped building its nest? Great Horned Owl? Did the GHO nest again nearby? 4. I have since noticed one grackle "standing on guard" perched on a phone wire looking directly at the nesting tree. I never thought about it before, but after this incident, I think that is what it may be doing. 5. I did see a grackle once dash into the nesting tree like a lightening bolt when a robin entered. Robin left promptly but lagged for a moment. *"Don't ask what the world needs.
