Our female red wolf has been in estrous now for over a week. Unfortunately, the keepers have not seen any mating interactions between the male and the female. There seem to be some differences from last year, as well. For instance, the male chased the female around quite a bit last year while she was in estrous. But I have not heard any other keepers mention that they have seen him chasing her this year. Just today, Cassidy played a video for me of the male wolf howling, which has been reported a couple times over the past week and is definitely out of the ordinary for him. I will keep you posted if we witness any other behaviors, but in the meantime keep your fingers crossed!
