Hi Fred,

We were at Mazatlan over Thanksgiving week. I didn't see the display
mentioned above but on the Terraza Playa restaurant deck every morning
[while we were consuming our Huevos Rancheros] there were a number of Rock
Doves. Quite common down there. We also saw quite a number of White-winged
Doves, about the same size. Could be what Friend <B> saw?

I'll try post a small trip report later.

Cheers,
