184 roosting together with another roost 10 ft away with 141, another with 112, and another with 56. All within about 50 ft of each other.

I checked the roost last night (10/3) around 8:40pm. Nobody checked that location this morning so can’t confirm they stayed all night, but I would imagine so.

The first time we had monarchs there was on Tuesday 9/29, 3. The next night there were around 118, I believe (don’t have access to the data at home, but I think I uploaded that point last night).

The roost trees were Huisache (Acafar plant code).

Counted individuals since there weren’t too many yet. We will be moving to cluster counts of 5 or 10 when it gets busier.

There is lantana and a waning bloom of cenizo.

It was not windy last night, but our winds are predominately out of the SE or SW most of the year. These monarchs are on a tree line facing NNW with a large berm behind the trees, so yes they would be sheltered from a typical wind here.
