The Eurasian Penduline Tit Remiz pendulinus was until recently considered to be an accidental winter visitor to Morocco. Regular wintering was suspected in the north-west of the country but had been poorly documented. The ringing data collected in the Smir marshes (north-west Morocco) during the period 2004-2008 indicate that Eurasian Penduline Tits regularly winter in Morocco. During the study period, 50 birds were caught on 68 occasions. The intra-seasonal recapture data, i.e. autumn to the following spring, and winter observations showed that some individuals over-wintered locally at this site. The inter-annual recapture data indicate that wintering birds return regularly to the Smir marshes.OSTRICH 2011, 82(1): 39–4
