The reporting rate for Willow Warbler highlights a late July / early August peak in records not seen in any other warbler species (though the Chiffchaff reporting rate does show a similar pattern in September). Quite what causes the wave of Willow Warblers at this time of year isn't entirely clear but one thing is certain: the 1000 individuals logged at Bardsey Bird Observatory on Monday 2 August (see Latest Wildlife Sightings) must have taken some counting!
