They work together and announce food sources... and the dinner bell gets rung...
many times i have noticed when filling feeders
how the calls go out alerting others to the new cache.
~ when out in Cal....
one day i hiked way up into the mountains with a backpack
...my lunch and a quality twenty pound bag of bird seed
of a mixed variety
and carefully selected a spot... of smooth rocks and trees...
and not a single bird to be seen or heard anywhere.
the perfect conditions........
i carefully placed it in every crevice imaginable especially in trees
and then spread the rest out in the open in a circle then i ate my lunch
and took a short nap... and hour and a half passed and nothing was seen or heard.
Then one small Bird happened by...
and rather than just eat....it flew up higher in a tree and started calling
and that brought more birds and then more birds called....
soon there was more than fifty...of many different species
and they were having a ball and i listened as each type made there dinner bell call
bringing in more of the same.
I've been doing this type of experiments for my whole life.
