Cuckoo Migration

ByRichard Nissen Reading Time: 1 minute
Cuckoo Migration is one of the great mysteries and to date there is still no agreement on how Cuckoos find their way to the Congo for the winter starting from different locations in Europe.
 
The team at Copenhagen University under Prof Kasper Thorup have been  able to tag fledgling cuckoos to follow their migration.  The link shows their results.  The British trust for Ornithology (BTO)  has been forbidden from tagging young birds as these are deemed too small to carry the extra load of a transmitter.  But you will see their results on older birds which seem similar to the fledglings.

I believe, that the way that swallows make this migration is by…

Migrant bird population declines, an African perspective

http://safari-ecology.blogspot.fr/2012/03/migrant-bird-population-declines.html This web site gives us some real insight into the migratory habits of birds in Africa.  Please follow the links too.  We are fascinated in Wheatears as they like the Bar-tailed Godwit they breed in the Arctic and yet make a remarkable straight great circle flight alone to their wintering grounds in Africa. It is wonderful to have…

Long-Distance Nocturnal Navigator

Warrant11 2016 Here is a fascinating paper about The Australian Bogong Moth Agrotis infusa: which is the most amazing  Long-Distance Nocturnal Navigator.  As they navigate at night their feat is perhaps even more amazing than the migration of the Monarch butterfly in the USA.

A conceptual framework on the role of magnetic cues in songbird migration ecology

This paper is difficult to understand but it summarises the work on animal navigation to date.  The key is that all the research which is confident that animals navigate using magnetic cues are not necessarily the whole story and that all navigators use all the clues they can get to help them.  Recently there was…

Mathematical analysis of the homing flights of pigeons based on GPS tracks

Ingo Schiffner At the RIN 11 Animal Navigation Conference Ingo Schiffner, presented a paper: Mathematical Analysis of Pigeon Tracks, characterisation of the underlying Navigational Process and now he has produced another paper covering Mathematical analysis of the homing fights of pigeons based on GPS tracks.  For me,  this work begins to create an underlying mathematical basis…
