There is a new hummingbird cam in West TX, operated by Cornell. They are doing Avian research there, banding hummingbirds, etc. They have identified 12 species migrating through the area; they have 24 feeders; they say they change the sugar solution every several days and use as much as 6-7 gallons during peak migration (now). The clarity is great, and they have a species key to help ID them. Enjoy:
