Spatial and temporal migratory patterns of trans-Saharan birds in the Iberian Peninsula
[eng] The spatial and temporal variability of migratory phenology of Ciconia ciconia, Cuculus canorus, Apus apus, Hirundo rustica and Luscinia megarhynchos were studied by means of 44000 records for 1400 spanish sites during the period 1944-2004. In all species, first individuals arrive to the south...
