JPMayers 1974 Parasitic jaeger Punta Raza, 15 Km N of San Clemente del Tuyu, by road, Ptdo de Gnel Lavelle, Pcia de Bs Aires, Argentina 28 March 1815 - jaeger coming down beach. 3rd one seen today, all of which have passed within 20 feet of us, flying low over head + affording an excellent look, tail is classic shape short barb2nd-3rd dark phase with very prominent white wing patches. I first detected it because of the uproar in the shorebirds - everything is in a commotion + flying - coalesced into a single 3 large flashes of 100+ birds / flock - mixed with WR, Chiloe, etc., Arenaria etc. Kelp gulls + flocks of terns also took off. The jaeger hunted gulls + terns in air. Then landed beside 2 Kelp gulls. The jaeger appears to be molting primaries now (or is it a bird WTE Rumboll tried to shoot?) 29 March 0950 - jaeger present on same mud flat this morning. It has been perched sitting in the mud well away from the tide line for over 20 minutes. No birds around it.
