Songs and Calls
As I was researching the piece on Chickadees in this issue of
BirdChat, I was reminded of the difference between bird songs
and bird calls. I thought I would explore that subject a bit further.
Here is what I learned!
A birds song is the repeated vocal display given by males
predominantly during the breeding season; song is used to declare
territory and to attract a mate. The Carolina Chickadees
song sounds like fee-bee fee-bay. The Tufted Titmouse
sings peter, peter, peter. The male hormone starts
the seasonal cycle of song; weather and length of day trigger
the production of the hormone. In some species, cardinals, bluebirds
and song sparrows for instance, the females also sing. In other
species, like hawks, owls, jays, and crows, courtship calls replace
song. Woodpeckers dont sing either, but declare their territory
and attract mates by drumming on trees
or the loudest downspout
on your house!
Calls are the vocal displays used by adult birds for communicating
alarm, distress, threats, and assembly. The most recognizable
call of the Carolina Chickadee is chick-a-dee-dee-dee.
This call is used in the fall and winter when the Chickadees are
in flocks to keep the members in touch with each other. And who
hasnt heard the raucous jay call when Blue Jays
encounter an owl in the woods!
Most birds use call notes year round to communicate with each
other; songbirds use their songs for territorial advertisement
and courtship.
