A ROCHA RINGING REPORT FOR 2020 Guillaume Réthoré In 2020, 57 ringing sessions and 4 ringing demonstrations were realized and 656 new birds of 46 species were caught and ringed at Cruzinha and Estômbar. The number of species is a little below average (Fig. 1) but the number of ringed birds is the worst ever (Fig. 2). This low number can be explained by a smaller ringing effort with fewer ringing sessions, like the absence of ringing at Ponta de Almádena and the few ringers who came to visit during the autumn because of the current pandemic (which reflects in the number of some species caught, such as Blackcaps). This however did not stop the weekly ringing at Cruzinha all year round.

The grand total of Iberian Magpies is now over 400 birds caught, over 2600 for the Blackbirds and over 2000 for the Pied Flycatchers.

The grand total of Short-toed Treecreeper is now over 70 birds and 2020 was the best year since 2015 (Fig. 9).

We caught the first House Martin since 2000 (a bird was ringed in 2011 but was brought wounded at Cruzinha) and the 1st Linnet, Grasshopper and Cetti’s Warblers since 2017. Two Cetti’s Warblers were caught, one at Cruzinha and the other at Estômbar where the A Rocha ringing team did a ringing demonstration. At least one Spotless Starling has been caught every year since 2014 and 44 % of all the Spotless Starlings were ringed between 2014 and 2020. It was also a good year for Nightingale, with 7 birds, a total not reached since 2014, but the phenology of some of these birds is interesting too. The two first birds were caught quite early, in March and the last one in November, probably one of the latest records in Portugal.
