The American Kestrel is roughly the size and shape of which bird?

The American Kestrel is indeed roughly the size and shape of a Mourning Dove. This comparison is based on the physical dimensions and overall body structure of the birds. American Kestrels are small falcons, typically about the size of a Mourning Dove, which itself is a small, slender bird. Both have a similar body length and are light in weight, which makes them comparable in terms of their build.

In contrast, the American Robin is larger and chunkier, making it an inappropriate comparison. The Peregrine Falcon is significantly larger and has a more robust body compared to the American Kestrel, while the Red-tailed Hawk is also much larger and has a different body shape, being sturdier and more powerful in build than a kestrel. Therefore, the Mourning Dove serves as the best comparison when it comes to size and shape due to their similarities in physical features.
