Tree Martins use relatively small hollows in the upper branches of trees. If necessary, when hollows are too big, they use mud to reduce their diameters.

The fact that Tree Martins are colonial nesters does not
mean that there are no fights over suitable hollows

Behaviour |
Social behaviour: Communal | Mobility: (Partly) migratory | Elementary unit: Flock |
Flocks of Tree Martins have the habit of returning to the same tree to nest in for many years.
Some of the photos above already show that Tree Martins are colonial birds. Below another example of this type of behaviour. Note also, based on photos shown above, that they have favourite nesting trees, to which they will return year after year.
