This sizable group of Hackberry Emperor butterflies is feeding on a sap flow. Joining them is a pair of slightly differently patterned Tawny Emperor butterflies as indicated by the red arrows in the first photograph. Can you see the difference?
This observation is the continuation of a previous post. The previous article can be found here: Red-tailed Hawk – Nest Update 3
On today’s visit to the Richardson Red-tailed Hawk nest, I once again found the female sitting high a top the antenna tower. The diligent mother hawk was keeping watch on her young while patiently waiting for her mate to return with his latest catch.
Once again, I only saw one juvenile hawk today. It is begining to appear as if one eyas is all we have at this nest. I will continue to monitor this situation over the coming weeks.
The male hawk did not make an appearance this time, but the female did have a couple of other interesting visitors while I was watching. The first was a Northern Mockingbird, probably with young nearby. This brave mockingbird made repeated attempts to drive the female hawk away by striking the big bird bodily. For her part, the mother hawk was generally unimpressed by the effort.
Later, I moved to a vantage point directly below the female hawk. There, I witnessed a Blue Jay make a similar attempt to drive away the hawk. The Blue Jay impacted the hawk several times and sent feathers flying on at least one occassion. Ultimately, this effort too was a failure. Our female Red-tailed Hawk is very dedicated to to her nest and her young.
This observation is part of a weekly monitoring of an active Red-shouldered Hawk nest. The last week’s observation can be seen here: Red-shouldered Hawk – Nest Update 3
When I arrived at the nest today there were no adults present. A juvenile could be seen, though, sitting high on the rim of the nest, hot and panting. Soon the adult female showed up. Strangely, she brought no food with her. Upon her arrival a second and then third chick became visible as they competed with each other for their mother’s attention.
