Migrant beret for the dark pardela
2006/10/01 Elhuyar Zientzia Iturria: Elhuyar aldizkaria
Researchers have found that the migration of the Shadowy Shearwater is representative in the record book: Travel 64,000 kilometers every 200 days, more than any other migratory animal.
Researchers have first analyzed the migration of this sea bird. To do this, the traditional tool has been replaced by another similar to that of fish, since it is lighter and allows tracking by geolocation. In addition, it saves the data in memory. They were able to find out where the birds were and where exactly they went, how much they dived into the sea for food and what temperature the surface water had.
In recent times there is less and less dark shade and the data collected will be very useful to know why this loss is occurring.
