JPMuers 1974 Journal Estancia Weedland, 35 Km S of Juanlicia by road, Pto de Ulladariaga, Pucicato Bs Aires, Argentina Pseudoleistes viridescens 110,0,0 Sicalis sp. prob. luteola 350,20,0 One of the highlights was the find of 3 banded Chardarus falllandicus - Mr. Ryle and Roly. see Ch. falllandicum, Oreopholus, Zonibyx sppacent. The decline in #s of Anthus conendera and Lessinia rufa is remarkable since my last outing over the llanos. Oreopholus and Zonibyx were much more common. Thincocus appear to be holding their own. 4 June rained most of the day, ceasing 1400 but remaining very #s overcast. Strong to moderate wind persisted all day out of # shifting SW in the afternoon. Sunset revealed a thin but growing line of cloud on sky on the western horizon. 1600-1730 I walked along the southern border from camp to the toward the east, following the fence for 1/200m and then working partway into a drying tule marsh via bogsaths. Behind the Estancia more (the woods around the house, composed of poplar and eucalyptus largely), is a large stretched pampa grass on a very sandy soil. The grass has however, + the tussocks are now beginning to fall. While the grass is very thick and in places impossible to penetrate. Many of the clumps are higher than my head (5'8"), but the bulk of the vegetation is a boat shoulder height down. Walking through the grass you occasionally, (frequently,) break into little groyne although having sometimes with a small pool of tule along the edge. There are invariably #s lower than the surrounding land, + ever water filled during the spring. Just before reaching tule is a stand of spartina, + then comes the marsh. Only after penetrating through tule to a considerably extent did we come upon any standing water. Standing half-hidden by the vegetation - either in pampagrass or tule - 'pishing' for birds proved to very effective Species attracted in this manner are have an * in the following list: Rhynchactus rufescens 2 Circus cinereus 1 Leptotila verreauxii 3 Mothuva maculosa 5 Milvago chimango 15 Guira guira 8 Ardea cocoi 1 Polyborus plancus 7 Cindodes fuscus 15 S.
