This video shows the movements of adult Galapagos albatrosses making foraging trips to the west coast of South America during the breeding season in 2008. Along with the birds' movements, this animation also shows actual patterns of wind (arros) and ocean chlorophyll (green) during the same time. By comparing the animals' movements with environmental data like chlorophyll (which represents food availability) we can see why these parents fly so far to feed their babies!

The animal movement data used to make this video are stored at Movebank, an online database of animal tracking data (movebank.org) in the study "Galapagos Albatrosses" and published in the Movebank Data Repository (doi:10.5441/001/1.3hp3s250).

This video was created by Matthias C. Berger and is associated with the following article: Dodge, Somayeh, Bohrer, Gil, Weinzierl, Rolf, Davidson, Sarah C., Kays, Roland, Douglas, David, Cruz, Sebastian, Han, Jiawei, Brandes, David, and Wikelski, Martin. 2013. The Environmental-Data Automated Track Annotation (Env-DATA) System—linking animal tracks with environmental data. Movement Ecology 1:3. doi:10.1186/2051-3933-1-3

Wind data shown come from the NCEP Reanalysis 2 dataset provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their web site at http://www.esrl.noaa.gov/psd/. These and other environmental variables can be linked to animal movement data using the Env-DATA Track Annotation Service at movebank.org.
