Field Journal Assignment 4

I started my bird watch at around 10 am on Wednesday March 15. I was birding for about an hour and the weather was sunny and about 35°. I was at my families home in Chittenango, NY for spring break so my birding took place in the backyard and I walked a little closer to the lake for part of it. The habitat is suburban, but closer to the lake it gets a little marshy. I saw a few species on this walk, closer to my house I saw a male and a female Northern Cardinal, and sitting on the lake were at least 30 Canadian Geese. I also saw some gulls flying but I couldn't identify a specific species.
The cardinals were not really interacting with each other at all as they were just eating seeds from a feeder, but occasionally they would chirp. The geese were all just sitting on the water and honking, this was probably to ward off any potential threats and establish territory. Comparing cardinal to goose plumage you can see lots of differences. Cardinal males are bright red and females pale brown with some red hints while geese have a black head, tan breast, and brown back with white spots on its check and butt. Goose plumage probably provides advantages when it is in the water to camouflage from predators. Cardinals get their red color from their food and then the bright red is used to attract mates. The geese that I saw were all just sitting in the water and this indicates that they were resting. This fit into their circadian rhythm because they most likely foraged earlier in the day and are now resting before they forage again.
I did not encounter any groups of small song birds on my birding trip so I could not try the spishing activity on them. I did it briefly to the geese but they didn't seem to have any reaction to it. I assume if done to songbirds it probably interests them and causes them to get drawn in.

Field Journal Assignment 3

On March 2 I started bird watching at around 11:40 am and stayed out until 12:50. I was bird watching on Redstone Campus as there are usually plenty of birds around there to observe. It was not terribly cold today at around 34°F. The habitat was suburban-like since there were dorm buildings and busy roads nearby. I could hear and see many birds out today. The three species that I could distinguish were 5 American Robins, 3 Black-capped Chickadees, and at least 20 European Starlings, though there were too many to count.
The robins and chickadees were mostly sitting in a tree and singing their songs. The robins would sometimes fly back and forth between the tree and the ground and the chickadees would jump around the tree branches picking with its bill. I assume the chickadees were looking for little bugs and other things to eat off the branches since it was a warmer day and they didn't spend as much energy on staying warm. I assume the same for the robins, except they were probably finding things to eat off the ground instead. The European Starlings were displaying much different behavior. Down the middle of the open area is a path of grass with no snow that I assume forms from some sort of pipe or heat running underground between buildings. The starlings spent most of their time all together in the grass, but when one flew away into the tree they all followed. They did this a few times, sometimes without me even noticing. I would look away for a second and when I looked back they had vanished.
All three of these species were probably spending their energy today on foraging and eating since they didn't need to conserve as much for heat. But on a colder day I'm sure you would find them nestled away somewhere, like in a snag or in a tree, sleeping and conserving energy. As it gets warmer they will probably start to spend more time out looking for food and soon start mating. Their diet right now probably consists of a few bugs, but mostly things like nuts and seeds. In the spring it probably is reversed and they eat more bugs.
Since I wasn't really out in the woods for my bird watch I didn't come across any snags, but there were a few trees that had some sort of bird made nest/structure at the top. Snags are important for birds, especially in the winter, because they can use them as shelter from the weather and predators. They can safely sleep there or hideout and be protected. Smaller bird species that don't really live with others probably utilize this more as they can fit in more spaces and are the most vulnerable.

Field Assignment 2

On February 19 at around 8 am I did my field observations in my backyard in Chittenango NY. The temperature was around 35° and cloudy. The species I observed were about 4 Mourning Doves and 1 Red-winged Blackbird. There were some other birds farther away that I couldn't distinguish but these two species were the ones that dominated my field observation.

The Mourning Doves were sitting in my backyard before I even started my observations, but as soon as I walked outside they flew away. Their flight was very sudden and their wings seemed to be moving very powerfully. They didn't fly very far just to some trees nearby. A little later the Red-winged Blackbird flew in, it was glossy black with the bright red so I was able to identify it as a male. The flight pattern of the Red-winged Blackbird seemed to be much quicker and their wings seemed to also be quicker than the Mourning Dove.

The shape and size of the wings of both species seemed to be elliptical wings. The had fast, powerful flaps and moved at high speeds. I saw both these species come to and from where I was in my backyard to trees farther away multiple times. When either of them were flying, there looked to be a lot of flapping and the patterns were short bursts of speed. A difference between the two that I saw was that the Mourning Dove seemed to have bigger stronger wings, while the Red-winged Blackbirds looked like they could've been more fragile. This however was a very small difference as they were about the same size. Flight pattern can be important to help identify species as they tell a lot about the behavior and area that they are present in.
