Interesting- that was the pattern when I kayaked out to the roost three years ago. A cluster of birds at Sunset Pt and vicinity in the gathering dusk, but not enough to hint that 100,000+ would shortly be assembling beneath the bridge.

That roost was also overwhelmingly female-immature types, although there were a small fraction of adult males mixed in (<1% if I recall correctly).

I checked out the north end of the Causeway from Sunset Point in Mandeville last night looking for hordes of Martins There were a couple thousand birds at most, and most were a considerable distance from the pier. There were no clumps or groups of birds out there, but they did seem to bunch up on the shore, sitting on light poles and such, before heading out. There were definitely adult males among them.

This evening I visited the martin roost at the Metairie end of the Causeway over Lake Pontchartrain. There were a couple thousand birds (past experience shows morning counts are usually much higher than evening). I have posted a grainy video on my blog,<<7CPYaukey...>%7Cf3b6410f4ff947e3908408d5dba9c547%7C31d4dbf540044469bfeedf294a9de150%7C0&sdata=FW7YJ3Evo4HQTrH2ADYRz8JxX6nI1DfjbkDB81HOeLY%3D&reserved=0>, along with a satellite image showing that the Mandeville roost is active again as well. There was not a single adult male among the c. 200 I inspected closely.

Good birding!
