Lone crow flies in and will then call out alerting to danger or food...
It's a very covert, organized operation. :lol:
Maybe the *scout* isn't labeled as such by its peers,,,, it might have volunteered for the position and might not play this same role later in the day; I really don't know and don't think it really matters.
For all I know, the crows name is Bertha. :wink:
