A few weeks ago, a bird ringing day was held at our farm El Cerro de Sevilla. An essential study method to understand the state of the ecosystems, which consisted of collecting from the nest boxes and natural nests, 4 species: little owls, long-eared owls, lagoon owls and kestrels that have nested on the farm.
Each animal was fitted with a metal ring containing a numerical code registered in a database where the date of ringing, the location and the species are reflected.
Thanks to the ringing, we can learn more about each species: its migration, longevity, mortality, feeding.
It is essential to know how and why populations change over time. For this reason, population monitoring is crucial to identify conservation problems and thanks to ringing we can carry out this tracking.
