Hummingbirds in the Garden

We got a hummingbird feeder for the backyard and they're already hovering around it.  The most we've seen at a time is two so far.

They were already attracted to our yard with our plumeria plant so it wasn't really a surprise to see them. One of them has a red throat.  Not this one though.  I haven't looked into it but I'm guessing it's a male thing?  Will have to look it up later.

Ok, it's later and yep it's a male thing.  The females have no red coloring.  It might be a mated pair then that we're seeing come around.  That would make sense since they aren't chasing each other off.  Hummingbirds can be territorial and aggressive to interlopers.

The cats have taken a keen interest in the hummingbirds coming around and have jumped at the window more than once trying to catch them.  We have since bought another hanger for the feeder and moved it further into the yard.  That also keeps the other birds away from it and less likely to scare each other away.
