When forced to choose, some songbirds prefer the company of their mates to a good meal.
Social living entails some compromise; that’s as true for birds as it
is for people. Foraging in flocks often means that some birds get a
little less food than they might by flying solo, but there is also
safety in numbers: flocks provide better defense against predators and
more eyes to watch for danger. For most, a little food for a lot of
security is a worthwhile tradeoff. Some songbirds, it turns out, are
willing to make even greater sacrifices for the sake of staying close to
their mates.
Great tits – small songbirds with yellow, black, and white feathers –
seem perfectly willing to spend time at a feeder where they can’t get
any food, in order to stay close to their mates who can eat there.
