Behavior

Penduline tits are extremely active and agile birds. Typically, they are found in pairs or in small groups. Forest-dwelling species spend much time in the tree canopy, using their agility to move through branches, sometimes nimbly making their way along the undersides of twigs and boughs. Like long-tailed tits (Aegithalidae), they may roost in groups at night. Verdins are of particular interest in their construction of roosting nests. These are similar to breeding nests but lack soft linings and are generally less "finished."

Penduline tits from north temperate areas migrate outside the breeding season; other species are largely sedentary.

Calls are high pitched and songs range from the rich vocalizations of the Remiz to the rather more repetitious Antho-scopus. They are territorial in the breeding season, but the territory is largely confined to the immediate environs of the nest. This small, defended area leaves room for possible semi-colonial nesting in species such as the European penduline tit.
