Still in Tuxpan

Island Girl has remained in the city of Tuxpan for the last two days. She is using at least two different cell towers, the original one located at the edge of the river and another situated inland about 700 yards north on top of a hill.

Both towers are visible by using the Street View icon.

Incidentally, to get OUT of Street View, click on the horizontal arrow in the box on the upper left of screen.

On Thursday, she was at the river site at midnight and 4 pm local time.

On Friday she was at the inland tower at 0800 and 4 pm local time.

She seems to favor stopping off in cities and perching on cell towers for a few days.

Usually, she does this down in Limon in Costa Rica.

Building up her fat stores? Building up her experience? Lots of easy prey? It would be good to know.

This seems like a good study for someone. It is probable that more peregrines than just Island Girl are using these towers and not only just during migration.

Might be interesting to look below many cell towers in Central America and collect prey remains to see what the falcons are catching and eating.

Seems like that would be a pretty easy way to collect a lot of data.

She's getting up there age-wise, like the rest of us, isn't she? Maybe she's looking for easier food sources for such a grueling trip?

Hi Anna,

Yes, you are correct. She has to be at least nine years old now, perhaps older.

You are asking a really good question. Do they physically experience a diminishing ability as they age? I am!

I don't think anyone knows the answer to that for peregrines yet. How would we determine the answer?

And specifically, how would they be affected?

When I look at how she began her migration this year, flying all the way across Hudson Bay on her very first flight, it is hard to say that she is slowing down.

And you would think that if she is experiencing physical problems, could she still fly so well and catch her prey?

Seems like she is doing fine in that department, at least for right now.

Many banded wild peregrines have lived into double digit ages. Let's hope she is one of them.
