Hi Fritz,
While I haven't come across another description of Blue Jays performing
this 'head down' behaviour, it is a known threat display of Semipalmated
Sandpipers. Since this is the time of year when Blue Jays start to
perform their social displays, you've probably witnessed a dominance
display taking place along these lines. I've had up to 35 Blue Jays in
my apple tree for the last two weeks, bopping their heads and calling,
perhaps males trying to convince females to ignore the mountains of snow
in this area and begin mating and nest building. I don't think the
females are falling for it...
All the best,
Lance

Subject: [NatureNS] Bird behavior question
Hi All,
While watching two Blue Jays squabble yesterday I noted a
behaviour that I hadn't observed before. Both birds stopped fighting and
placed their heads, opposite each other, flat on the surface of my deck
where the dispute was taking place. They repeated this action a few
times holding the position for a few seconds each time. One bird then
flew off and the remaining bird did the action one more time before
leaving.
Has anyone ever seen this behaviour? What was the meaning of
this odd behaviour? All the best.
