[Birdnet] Black Rosy Finch Roost

[Kevin Colver]

Greetings all,
Historically, Black Rosy-finches have been observed to winter at  
night in large groups in caves or abandoned buildings.  I am working  
on vocalizations for this species and would like to observe and  
record this behavior.  Does anyone have information regarding the  
location of such a roost this year?  If the information is  
confidential you may reply to me off list.
Thank you,
Kevin Colver
