Territoriale en broedende Visarenden Pandion haliaetus in Nederland in 2014-2019: een aanvulling

In a previous paper on the trend and breeding success of Ospreys in The Netherlands in 2014-2019, part of the text went missing. It involved the breeding series in the southern section of the Biesbosch, starting with nest building in 2014 and 2015, and two more nests in 2016, all of them in electricity pylons. The nest built last, in August 2016, was occupied in 2017 and resulted in three fledglings (fledging date c. 24 July). This nest was used by a Peregrine Falcon Falco peregrinus in 2018, and the Osprey pair (female with black colour ring and metal ring, not sure whether the same as in 2017) resorted to building a new nest and several nest foundations in electricity pylons, without laying. One of these nests was used for breeding in 2019, with a single chick ringed and colour ringed on 10 July. The female was the same as in 2018.
