| Abstract: | [eng] Notes on the foraging behaviour of the Balearic shearwater Puffinus mauretanicus. This note describes the foraging behaviour of a mixed flock of Balearic and Levantine shearwaters, observed during the month of January, just off the coast of Mallorca. The birds moved in a group and dived in the sea with hthe wings partially folded. A second immersion on the same spot started on the sea surface, but then the birds had their heads underwater looking for a potential prey. The wings were beaten underwater. Sometimes the depth reached was a few centimetres under the surface, but also, depths of up to two metres were reached. The maximum period underwater was 30 seconds, and all the prey was swallowed before surfacing. |
