<< Back to This Week's Update

The most important data we gather in our hummingbird study are arrival dates. This helps us and other scientists see how the migrations move forward. But more detailed observations can inspire insights into hummingbirds and their migration — and new questions to investigate. As you read the reports below, do this:

• Find 2 observation details that make you wonder something. For each one, write a possible investigation question.
  (Sample question using the March 11 sighting: I wonder if hummingbirds will choose plant nectar over feeder nectar if they have both options.)

March 11: Mandeville, LA
(30.36 N, -90.04 W)
I saw hummers quite a few times on my shrimp plants which are blooming now. I have a feeder out also, but they are going to the plants. >>

March 13: Gainesville, FL
(29.65 N, -82.33 W)
Saw my first male rubythroat at my porch feeder about 1:00 p.m. He looked really good for a hummingbird that has traveled so far. I think he is home for the summer as he went to the same feeder as he did last year. The ruby acted like he knew just where it was and had been here before. >>

March 17: Gulf Shores, AL
(30.25 N, -87.81 W)
I have had two feeders out since March 7th. Finally I walked by the window and a female rubythroat was sitting on one. We are on Fort Morgan Road, six miles from the end of the peninsula and 1/4 mile across the street from the Gulf. It was 8:30 a.m. on a cloudy morning. >>

March 15: Issaquah, WA
(47.44 N, -121.98 W)
We've been waiting for the first Rufous this year. With intermittent snow this last week, they've probably been waiting too. Our first sighting was 3/13/09. A confirmed male Rufous hummingbird was at the feeder on 3/15. It had red/rufous shading on its back and shoulders. >>

• Reports from Other Observers: You can find all observations reported this week in the sightings database and on the on the rufous and rubythroat migration maps.
