Naish Ocean and Earth Science, National Oceanography Centre, University of Southampton, Southampton, UK Keywords Abstract birds; Avialae; fossil; behaviour; palaeontology; ecomorphology. Between the Middle Jurassic and Holocene, birds evolved an enormous diversity of behaviours. The distribution and antiquity of these behaviours is difficult to Correspondence establish given a relatively poor fossil record. Rare crop, stomach and gut contents Darren Naish, Ocean and Earth Science, typically reveal diets consistent with morphology but stem-members of some National Oceanography Centre, lineages (including Cariamae and Coraciiformes) seem to have been different in Southampton ecology from their extant relatives. Most of our ideas about the behaviour of fossil University of Southampton, Southampton birds are based on analogy (with skull form, limb proportions and claw curvature SO14 3ZH, UK. being used to guide hypotheses). However, this has limitations given that some Email:

Reductionist methods have been used to test predation Editor: David Hone style and running ability in fossil taxa including moa, Gastornis and phorusrhacids. Virtually nothing is known of nesting and nest-building behaviour Received 18 July 2013; revised 11 but colonial nesting is known from the Cretaceous onwards. Rare vegetative nests December 2013; accepted 17 December demonstrate modern nest-building from the Eocene onwards. Ornamental 2013 rectrices indicate that sexually driven display drove some aspects of feather evo- lution and evidence for loud vocal behaviour and intraspecific combat is known doi:10.1111/jzo.12113 for some taxa.
