AgCPA just about covered the bases. One thing I like to stress is adding native flowers to your garden. Things like
lantana,
purple mist-flower, or
Turk's cap are good for both butterflies and hummingbirds. The
Lady Bird Johnson Wildflower Center page is an incredible resource. Locally, check with the
Brazos Valley Master Gardner's group- I think they're going to be at Boonville Days at the Museum of Natural History on 05Oct. Any hummer feeder from a big box store will suffice. Just make sure the sugar water doesn't get cloudy- 1 part white cane sugar to 4 parts water. No red dye needed.
As for the hummers,
Rufous and
Allen's are kind of odd balls for our area. We had two Rufous at the house back in August on their initial fall migration. In the winter, usually young or not-quite-full plumaged adults will over-winter along the Gulf coast instead of going to Mexico, as there is a bounty of feeders up. Since they aren't adults, they will still look greenish, but there will be a few glimpses of orange on their bellies and base of tail. It's not obvious at first, but a little bit of time spent studying them with binoculars will help. We usually see winter hummers just after sunrise, but others see them more often.
Lol FlyRod- that Eccell Costa doesn't look like the Costas in my books... must be a local variant!
