For those of us following the BTO satellite tagged Cuckoos, we can see Spring is well on its way – three birds have already left their winter locations in the Congo rainforest and are at their stopover sites in West Africa.
Later this month, rested and loaded with the fat that will fuel their journeys, they will head north across the Sahara. Fingers crossed for good weather and a safe flight.
Professor Kate Jeffery of University College London gave the annual address to the Royal Institute of Navigation (RIN) this year (2014). This article published in RIN’s Navigation News is, for me, a seminal step forward in describing the parameters of animal navigation and building a structure to delve deeper into how navigation might work. Her idea that…
There is a lot of work going on in the navigation field. All the researchers in this field are now clear that navigation takes place in the sub-conscious. I made the mistake of thinking that native peoples who seemed to navigate perfectly without any aids could tell me how they did it, but language is…
Please find this PDF which follows a lot of research on Albatrosses. This presentation throws up some really interesting issues. I feel comfortable that albatrosses when they decide to go home follow their sense of direction to their home islands in the South Atlantic: the Crozet Islands and Kerguelen as they fly straight there. However, please…
Atchoi, E., Mitkus, M., Vitta, P., Machado, B., Rocha, M., Juliano, M., Bried, J. & Rodríguez, A. 2023 Ontogenetic exposure to light influences seabird vulnerability to light pollution. Journal of Experimental Biology 226. doi: 10.1242/jeb.245126. Atchoi 2023 (no pdf) Light pollution critically affects the fledglings of burrow-nesting seabirds, leading to massive mortality events. The successful management of this pollutant depends…
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….
By Professor Gary Ritchison of the University Works at Eastern Kentucky University in Richmond Ky, USA. His long-term interests have been in avian mating strategies, specifically examining factors that influence mate choice (and choice of extra-pair partners) by female songbirds and avian vocal behaviour (particularly the functions of song), the ecology and behaviour of grassland…
