After all that dancing and display to get the females attention and favoring him for mating he leaves and does not participate on rising the chicks? Well at least she incubate her own eggs and do not also leave them like the cowbirds where neither parent are involved in rising the chicks.

I do notice some birds being a little aggressive at our feeders especially the red-bellied woodpeckers with their sharp beaks. Even some of the Mourning Doves are! Hummingbird males are something else! Fancy dancers! I don’t know how the females do it. I guess they must have to leave the chicks to go find food. I thought the expandable nests were cool too! So amazing! I will have to checkout the Woodcocks!

Expandable nests, how cool is that! Only 2 eggs. Courtship displays are so elaborate & expend so much energy with repetitions. After all that work, they maybe mate & then they’re done! No further involvement. Altitude migration of Hillstar & torporing down to 38° F is unique.

In some of the other bird species that visit the neighborhood, males and females spend more time together as couples and share parenting behaviors. Male house finches appeared to do much more work than females in raising young outside nests. Male cardinals feed young and even feed the females. Hummingbird courtship looks exciting and bold - like their coloring, as compared to other northeastern bird species. To be honest, however, I have almost no knowledge of other bird species attraction behaviors - just haven't heard of anything exotic. Many others do migrate, and all eat, sleep, makes nests, etc. Also, a few other species have gone into torpor at the feeders in the back, for up to 20 minutes - including a white-breasted nuthatch who was perching facing bill down. That looked dangerous, as hawks come by occasionally.

Hummingbirds and Towhees are fairly common in my area. On a cursory glance these birds are similar in their drive to raise young, find food and clean water, and use songs for communication. (There are probably more similarities that I cannot think of right now.) As for differences, I have noticed a few more between these two birds than their similarities. It seems only the hummingbirds in my area migrate (not the Towhees), hummingbirds and Towhees eat different food, both Towhee parents seem to raise their children together, and Towhees don't seem to be as territorial as hummingbirds.
