I agree, it is important to track these birds. Especially as it seems they have adapted quite well and are spreading. Perhaps, we will see them expand like the Monk Parakeets.
I had an encounter with the said species this year at Bush Terminal Piers Park, in October. A total of 4 birds with no bands and they acted like true migrant birds on the move. Since we are on the topic of scientific uses of our field efforts. I would like to see the eBird "think tank" devise a way to track feral cat populations at hotspots. We might find that data to be useful in helping understand the decline in numbers of birds and other wildlife at these sites and could be used down the road in getting colonies removed. I have been doing just that for many of my sites I tend to cover. But that, is another conversation for another time. Carry on then.
