Note unusual thick bright white under feathers; UPDATE: 3/8/22-Female crow due to clicking call.
観察結果の詳細
Raven making click calls and then probably it's mate came and they began calling to each other and were making more caw type noises. Audio and photos will be uploaded shortly. UPDATE: I just looked at the photos and I don't think these are Common ravens, but I don't know what they are. The one I got the photos of has tons of white inner feathers like Chihuahuan Ravens have, but they supposedly don't live here. And it's beak is not as curvy as a raven's beak, but it's got some long nasal bristles in one photo. And then it has this white furry undercoat that's super fluffy and thick and white, and I cannot find any photos of any American Crows or Common Ravens with similar white feathers underneath that is as contrasting and intense like this bird has. I've also never heard any crows make clicking noises like this bird made but perhaps it's just a first. In any case, since I'm no longer confident in saying this is a common raven, I'm changing this from common raven to crow/raven sp. See photos & audio file. UPDATE 3/8/22: (I just learned from reading Dr. Kaeli Swift's Corvid research blog, that the call this hostess cupcake corvid was making is a distinctive call only made by female crows, i.e., the knocking, rattle clicky call in the attached audio file. Based on same, I'm updating this from crow/raven sp. to American Crow, and putting the hostess cupcake crow down as female).
