Two Hummingbird Sightings

This tiny hummingbird was playing in the sprinklers way back on the morning of Sept 4th. I am fairly certain this is a female (possibly immature) Black-chinned hummingbird, (Archilochus alexandri).

I find it hard to distinguish the female Black-chinned from the female Ruby-throated hummer - I am using the medium gray streaked head to make the ID on this one. (Males would be much easier to tell apart!) It was fun watch her fly in and out through the sprinklers. Here's a photo:


Yesterday (Sept 15) I finally hung up my hummingbird feeder... better late than never I suppose. A female Ruby-throated hummer (Archilochus colubris) visited almost immediately and came back several times but I was not able to get a photo of her. Every time I made the slightest move she flew away. She returned just once today but I still wasn't able to get the shot off before she flew away.
