The genetics of bird migration: stimulus, timing, and direction

Ibis, 1992
The extent to which genetic factors are directly involved in the control of bird migration and the mode of inheritance involved has been studied systematically over the past 15 years in the Blackcap Sylvia atricapilla by cross‐breeding and selective breeding. Results have also been obtained from a few experimental and field studies on Robins Eritfiacus

Directional Selection and the Evolution of Breeding Date in Birds

Science, 1988
In many bird species, those pairs that breed earlier in the season have higher reproductive success than those that breed later. Since breeding date is known to be heritable, it is unclear why it does not evolve to an earlier time. Under assumptions outlined by Fisher, a model is developed that shows how breeding date may have considerable additive ...

A direct cerebrocerebellar projection in adult birds and rats

Neuroscience, 2000
The rostral Wulst of birds, like the somatosensory cortex of mammals, receives somatosensory information from the thalamus and projects to the brainstem and spinal cord via a pyramidal-like tract. Using anterograde and retrograde tract-tracers, we show here, in adult zebra finches, that the rostral Wulst also projects directly to the cerebellar cortex ...

The Water Framework Directive and the Habitats and Birds Directives

2009
The Water Framework Directive not only describes a new method to classify and enhance the status of waters in the UK, it also provides new obligations, a new management framework and additional monitoring requirements for water dependent Natura 2000 protected areas. Most importantly, it requires the achievement of any standards and objectives for these

Offsets and Conservation of the Species of the EU Habitats and Birds Directives

Conservation Biology, 2013
Abstract Biodiversity offsets are intended to achieve no net loss of biodiversity due to economic and human development. A variety of biodiversity components are addressed by offset policies. It is required that loss of protected species due to development be offset under the EU Habitats and Birds Directives in Europe.

Magnetoreception in birds: no intensity window in “fixed direction” responses

Naturwissenschaften, 2009
Under 502 nm turquoise light combined with 590 nm yellow light and in total darkness, European robins, Erithacus rubecula, no longer prefer their migratory direction, but exhibit so-called fixed direction responses that do not show the seasonal change between spring and autumn.

[Birds' sense of direction].

Duodecim; laaketieteellinen aikakauskirja, 2016
Birds utilize several distinct sensory systems in a flexible manner in their navigation. When navigating with the help of landmarks, location of the sun and stars, or polarization image of the dome of the sky, they resort to vision. The significance of olfaction in long-range navigation has been under debate, even though its significance in local ...
