Is it a bird?… Is it a plane?…

It’s a Cecropia Moth. It was spotted resting in a cherry tree in the East Lake area on Saturday morning before carrying on with its journey.
Here are some informative facts from Wikipedia:
The Cecropia Moth (Hyalophora cecropia) is North America’s largest native moth. It is a member of the Saturniidae family, or giant silk moths. Females with a wingspan of 160 mm or more have been documented. It is found as far west as the Rocky Mountains and north into the maritime provinces of Canada. The larvae of these moths are most commonly found on Maple trees, but they have been known to feed on Wild Cherry and Birch trees among many others.
The life cycle of the moth is much like any other saturniidae species. It lays oval-shaped, light brown eggs on the leaves of the host plant. When the eggs hatch, small black and hairy caterpillars emerge (first instar), and eat their eggshells.
Sometimes the newly hatched caterpillars have yellow bristles, which darken in a few minutes. As the caterpillars age, they molt 4 times. The second instar is yellow-green with black spots and spiny orange, yellow, and blue knobs. The third and fourth instars have smaller spines, and are similar to each other. The fifth instar is a whitish color with bright yellow, blue, and red knobs. The caterpillars feed heavily on their host plant and can grow up to five inches long. They then spin cocoons of brown silk, usually wrapped in leaves of the host plant. They then pupate inside the two-layered cocoon. There is only one brood per year, the cocoon overwintering and emerging in spring. When the adults eclose, they have to pump fluid into their wings to extend them. Because the adult moths do not have mouth parts they are unable to eat. As a result, the lifespan for an adult Cecropia moth is generally only 7 to 10 days in the wild, perhaps a little longer or shorter, depending on how much movement the moth makes. For instance, if temperatures are cooler, the moth may remain mostly inactive, which will increase its lifespan.
