The weather was very beautiful today and I was eager to go out into the woods. This morning I was woken up by birds, many many birds. There were European Starlings, Blue Jays, Black Capped Chickadees, Dark Eyed Juncos, American Crows, and more, all chatting away outside my building. One Starling even perched on my window ledge, let out a loud chirp, and flew away, perhaps just making sure I was awake and listening to their calls. The Starlings were, and typically are, the loudests birds this morning. There were many of them, and they were chatting quickly with each other. I noticed they were the loudests and making the most noise when moving locations, taking off and landing. Birds often talk to each other when they’re agitated, so perhaps these Starlings, constantly taking on and off, were bothered by something, maybe the presence of the many other birds. They also mostly called out from the highest possible perches, so their calls traveled as far and clearly as possible. Starlings are commonly very noisy, and move in groups. They are constantly communicating with each other, and use many different calls. Mimicry allows Starlings to have a very strange and broad range of noises, giving them a toolset for very complex conversation. The sound clip I attached to this observation is from this morning, taken through my open window on the 6th floor of Jeanne Mance. Apologies for the loud trucks.
Moving away from this morning, after class I made my way deep into Centennial Woods, to a marsh clearing between blocks of dark tall evergreens. I sat facing the sun, soaking in the warmth and looking forward to spring and summer. The slow, warm breeze rustled the tall reeds, and carried the clear whistles of many talkative birds. I quickly picked up on many chickadees, who sounded very close. They talked with short chirps, not their songs or warning calls. They were just chatting, with the purpose of communicating about food and locations, day to day business. I took this chance to test out “spishing”, and naturally, I felt a bit foolish. I played around with the sound of it, and soon the chickadees began flying around me. Around four of them flew over my head and landed on a tree right by where I was sitting. They began foraging at the tree. I continued to “psh”, and noticed a few of them briefly looking my way. Then all but one flew farther off into the clearing, with one chickadee still foraging around the tree. I felt silly making the noises but it was incredibly fun to be up close and started down by some chickadees. I believe these noises may call their attention because, depending on how you make the noise, a small bird may think the sound is an insect they could eat, or perhaps another bird they want to get closer to or farther away from. Or perhaps the “Psh” doesn't fool them, but just alerts them to your presence. This is a noise humans have been known to make trying to attract birds attention, and perhaps the chickadees have associated this “psh” noise with humans, and they just want to check you out or stay away!
The chickadee that remained at the tree near me was flying around it, resting on low branches, going down to the floor and back up to the top of the tree, occasionally flapping its wings quickly, hovering in the same spot for a second. The chickadee was foraging all around this tree, looking for most likely any insects on the bark, or seeds by the floor. They have fast metabolisms and move quickly, darting around for food. This chickadee was eating around mid-day. Today was a sunny, warm day, so perhaps the chickadees were active for more of the day than usual, taking in the spring weather. The Black-Capped Chickadee has, of course, the characteristic black cap. This specific coloration may be evolutionarily advantageous for warding off predators when they chickadees are facing the wood, with the black cap making the small birds seem less easy of a target. This usage of plumage is shown in Woodpeckers. I saw a Downy Woodpecker during my observations, it was pecking at a snag near where I was sitting. The red dot on the back of their heads can be used to fool predators into thinking they’re looking that way, or just are not to be messed with, while they are focused on the tree. The black of the chickadee may also be used to reflect light, as there's black banding above and below their eyes, which helps protect the eyes from bright sunlight.
As I was leaving the clearing, three Red Tailed Hawks soared right above me. Two of them stuck around for a while, circling right above me and flying around the clearing, hunting for something good to eat. It almost looked like they were dancing with each other through the air, passing over and under each other in wide circles. They were beautiful and huge, undeniably powerful. We stayed by each other for a while, until the hawks flew far off to the North and I continued my walk back through and out of the woods.
