Greetings All,
I should point out that there needs to be enough Snowy Owls around to be communal. The instances of Snowy Owl congregations that I know of have happened during big invasion years, with many birds present. During such years, in WA state anyway, about half or so of the Snowys are found in these communal roosts (they don't seem to be hunting at the time), sometimes with several birds on a couple adjacent large logs, or a group scattered across a few hundred yards' worth of debris near, or in, coastal marshes. For instance, there are 8 Snowy Owls in WA now (out of about 12 on listserv reported), together on a spit of land about 1 mile long and 1/2 mile wide. if they are acting per usual there, this is a traditional gathering place, all 8 are probably in an area about 1/4 by 1/4 mile. There is much similar habitat scattered in the region, but they seem to choose to hang together. But you need 8 birds in the vicinity. Two others were on the same stretch of dike, no more than 1/2 mile long, at another location.
