Extensive ringing programme of Black Stork juveniles in Latvia started in 1990. Up
until 2017, 1,603 juvenile storks had been ringed. In 2011, first remote sensing cameras
were installed, and one of the nests has been permanently observed with a webcam
since 2015. As of 2016, data from 20 cameras can be explored simultaneously.
Obtained material comprises more than 1.2M pictures collected near 92 nests. From this
material, more than 772K pictures from 41 nests, along with the videos filmed at two
webcam-equipped nests, have been used for analyses of territorial behaviour and mate
choice during the breeding season. In this talk, I discuss the validity of the widely
explored concept of the "territorial” or “non-breeding pair" – a parameter that strongly
affects all indices of productivity for any given territory. The data obtained exclusively
from observations of ringed individuals with known sex and other individually
identifiable birds suggest that this term is not relevant for Black Stork, consequently, all
breeding success data should be reassessed. Similarly, the assumption that males own
the nest appears not to be correct at least in some cases. The question whether it is true
only for Storks in the surveyed range or characterises species as a whole should be the
subject of a wider study over much larger territory in the future.
