Suburban wildlife

Yesterday it warmed up to nearly 60 degrees! A beautiful day.

The birds were out playing and sunning. I took the opportunity to play with my new lens that I got for Christmas. So happy with this result. The new lens zooms to 300mm and has image stabilization so I don't need a tripod to be able to get a clear, crisp shot of this little hummer up in the tree.
I expect the hummers weren't so happy seeing this guy invading their territory.
This little birdy hangs out in the wisteria brumble. Is it too soon to be nesting? I don't see a partner. I need to put out some water for her. Jimmy insists there's a lot of water out there for the little birdy to fly to, but I'd feel better if I had a little bird bath or something. Otherwise, why would she be hankering for sugar water?
I don't know anything about birds.
