{"assetFormat":"ePub","description":"For many people, watching and studying birds is exclusively a day time
activity. However, for many birds twilight and night time are not a
barrier to useful activity. It is true that very few birds are
exclusively nocturnal, but many birds which are active by day also
conduct limited, and often crucial, activities after dusk. This book
examines many examples of the nocturnal behaviour of birds; from the
occasional night feeding of wildfowl and shorebirds to the night
singing and night migration of certain passerines, and from the
location of nest sites by sea birds to the nocturnal foraging of owls
and nightjars. The special cases of flightless nocturnal birds and
those birds which dwell in lightless caves are also considered.

Throughout,
this survey considers not only what it is that birds do at night but
also discusses how these nocturnal activities are possible. It brings
together studies in field ornithology, sensory science, ecology and
physics and involves comparisons of the sensory capacities of other
animals, including man. It is shown how the senses of hearing, smell
and touch, as well as vision, play a crucial role in many of the night
time activities of birds.

However, these senses are not always
adequate for fully explaining how nocturnal behaviours are executed. To
achieve this we must look at the complex of relationships between
behavioural and sensory adaptations and the particular environments
which birds inhabit from dusk to dawn.","tableOfContentsSource":"/products/birds-by-night-graham-martin-v9781408137703/table_of_contents","additionalIdentifiers":{"additionalPrintIsbns":null,"additionalEisbns":null,"additionalIdentifiers":null},"isOnlineResource":false,"isOnlineResourceBundle":false}
