I suspect that this is a female Raccoon who is pregnant. They have their kits April - May. This nest box is not large enough for her to have kits in it, so I doubt I will be able to see them. She's been a lot of fun to photograph during my social distancing due to COVID-19. UPDATE: Yes, there is at least one kit!!! You will notice, in some of the photos, that she has a VERY short tail and I suspect that I will recognize her next year, based on her short tail. Some of the yawning photos show that her top teeth are very worn down, making me think that she is not a young raccoon. I was able to photograph her for almost all of the month of April, 2020.
