Neotropical bird migration

[(John Leonard)]

I've recently been thinking that, despite the larger outlay, the dollar
value of a bird tick is now getting to be cheaper OS than here, for me.

So I've been having Costa Rican thoughts. I know that for Central America
the time of the Neotropical migartion is best, but when does this happen in
Central America, March, April, both these months, or only one or two weeks
within these months? And is there an analogous return in the autumn, or is
this spread over a much longer period, as in Europe?

Thanks
