Behaviour and parental care of Skylark Alauda arvensis chicks
I studied parental care and fledgling dispersion of Skylarks Alauda arvensis during the last 4 days of the nestling period and the first 4 days after the nestlings left the nest but before they were able to fly. The study compared parental care in three different crop types: spring barley, grass and...
