We wanted to give everyone an update on the post-release pelican study from the Refugio spill, now almost one year ago. You may recall that 12 oiled pelicans and 8 control pelicans were outfitted with satellite tags so we could compare their movements and survival. In addition, all oiled pelicans that were released (not just the satellite tagged pelicans) got a green color band. Please report all pelicans with green bands to us here if you see them. While you are out looking for pelicans, if you do happen to see any with blue bands, please report those birds to International Bird Rescue. Even though we have a few control birds from this study that are sporting blue bands, most of the pelicans out there that have blue bands were rehabilitated by International Bird Rescue, and getting reports on where these birds are is extremely valuable.
Currently we have about 6 or 7 birds still transmitting. Two birds, one control and one oiled bird, have made some trips to Anacapa Island as if they were thinking about breeding, but they haven’t been there lately, so it’s unlikely that they are breeding.
A couple of control birds are hanging out in San Diego, and one of the rehabilitated birds is at a large lake in Baja California. Two other rehabilitated birds are in Baja; one is traveling north in the Gulf of California, and the other is in the central part of the Gulf of California. This last bird is a challenge . . . his satellite tag has stopped transmitting for extended periods of time, and then suddenly starts transmitting again right about the time we’ve decided the bird (or the tag) is dead. I’m going to give him the benefit of the doubt for as long as possible!
This May 7th, Audubon California sponsored a Brown Pelican Birding Blitz, where members of the public were encouraged to go find and report pelicans (AND maybe see some color-banded birds!). We are waiting to hear if anyone saw our green-banded birds! More information about the Blitz can be found here.
Here’s a map of the pelicans from the past month. If you look carefully around Los Angeles, you can see a bit of yellow peeking through — those dots all got covered by the bird in red. And near San Diego, you can see some blue dots . . . . that’s our bird with the satellite tag that seems lazy.
