Why do birds in colonial roosts roost?

In addition, there is some evidence that birds in the lower positions in colonial roosts lose heat because the rain of droppings from higher birds reduces the insulating properties of their plumage. It thus seems unlikely that thermoregulation is a prime reason for communal roosting in most species.

Do birds roost alone or in groups?

Some change their roosting habits with the season: male Red-winged Blackbirds usually roost alone on their territories when breeding, but crowd together at night during the rest of the year.

Why do we need birds to protect trees?

When insects like caterpillars, beetles or aphids invade our trees, birds can help keep them at bay. Many birds eat the tree pests we want to get rid of.
