In most avian species the plumage also has an important extra function compared with the pelage of mammals: flight. Accordingly preening, as a behavior that conditions the bird's integument, can be expected to play a more important role within the activity repertoire of birds than grooming does in that of mammals. Indeed preening is generally a very elaborate behavior that takes up a considerable proportion of the time budget of birds. For example, van Rhijn 2 has impressively documented the… 
Elaborate ornaments are costly to maintain: evidence for high maintenance handicaps
It is suggested that high maintenance handicaps are present in a variety of animals because of the time and energy required to maintain them in good condition.
Do peacocks devote maintenance time to their ornamental plumage? Time budgets of male blue peafowl Pavo cristatus
This paper explores another potential cost of ornamental plumage, which is the daily time and energy investment required to maintain the plumage in good condition, and investigates whether any additional cost should make the signal even more “honest”.
Behavioural neurobiology of feather pecking
Differences in feather pecking behaviour between HFP and LFP chicks can already be observed at a very early age during development, and the results indicate that HFP-LFP chicks differ in the way peading behaviour is targeted.
Variability of forage pecking in pigeons.
It is concluded that the pecking of pigeons exhibits a remarkable flexibility that conforms poorly with a fixed action pattern characterized by accelerometric/videographic technique.
Coping behaviour as an adaptation to stress: post-disturbance preening in colonial seabirds
This work combines two existing modelling approaches – logistic regression and Darwinian dynamics – to explore theoretically how a behaviour with crucial physiological function might evolve into a coping behaviour in the presence of predators.
Daily Rhythms of Female Self-maintenance Correlate with Predation Risk and Male Nest Attendance in a Biparental Wader
Investigating the daily rhythms of sleep and feather preening in incubating females of the Northern Lapwing, a wader with a highly variable male contribution to incubation, found that the female's sleep frequency peaked after sunrise and before sunset but was low in the middle of the day and especially during the night.
Behavioral Responses of Captive Corvids to the Presence of Visitors
Overall, the results indicate that corvids, housed in a wildlife park for several years, still show behavioral responses to the presence of human visitors in close proximity to their enclosure, and that the described behavioral changes are not indicative of any negative welfare impacts of visitor presence.
Stopover biology of Ruby-throated Hummingbirds (Archilochus colubris) during autumn migration
It is estimated that males and older birds were capable of longer potential flight ranges than either females or younger birds, and there is only weak evidence for sex-dependent migration.
Behavioural alterations in domestication process: Comparative studies between wild, captive and inbred red-crowned cranes (Grus japonensis)
Five main behavioural patterns of Red-crowned cranes include resting, moving, preening, feeding and alerting were identified by all occurrence sampling and instantaneous scanning sampling methods.


The patterning of body-care behaviour in the Herring Gull has been studied by means of: (a) qualitative observations on four individuals, and (b) application of six quantitative analytical methods on
Preening of Two Tern Species. a Study On Displacement Activities
The occurrence of preening 'during brooding' in most cases is thought to be caused by disinhibition and further by (probably permanently present) activating factors for the preening system, as well as inhibitory relations between various behaviour systems.
Social especially agonistic behaviour in the pigeon
The results obtained do not suggest a build-up of an "aggressive drive", during the periods In isolation, which is expressed through the performance of aggressive behaviour after isolation, and it was shown that diurnal rhythms did not affect agonistic behaviour.

Apomorphine pecking in the pigeon.
It is concluded that apomorphine exerts an excitatory action (direct or indirect) on the hypothalamic feeding centers; hence apomorphicine pecking can be considered as a pharmacologically motivated behavior.
