Expedition to Tierra del Fuego – 2004: Introduction

Share

On our fifth campaign to Tierra Del Fuego, we hope to achieve a variety of scientific and conservation goals focused on the red knot and their chief non-breeding or wintering area on Bahia Lomas. Guy Morrison and Ken Ross will continue the aerial survey of all shorebirds species along the Atlantic coast of Argentina and the Chilean coast of the Straits of Magellan. Our main team, composed of Chilean, Argentine, Dutch, Canadian and American biologists, will conduct several projects including red knot capture and banding, foraging efficiency, and invertebrate prey inventory. Concurrently, we will continue our effort to assist Chilean…

Previous Post The moon, tides and sun restrict our trapping effort significantly. The moon rises just as the sun sets, leaving us with too much light to catch birds with our mist nets. Bahia Lomas has two zones important to the birds. The normal daily tide floods about half of the sand and mud flats along the bay and in that littoral zone exists most of the red knot and Hudsonian godwit prey. The upper flat only floods at tides influenced by the full and new moon, rising more than 3 m. In that zone, prey densities are very low…

Previous Post We knew on arrival that trapping birds would be difficult; it turned out to be much worse than expected. In the last four days we spent much of the night mist netting from dark to just after high tide getting back to camp no earlier than 2:00 a.m. We ran mist nets each night from the 7th through the 10th and made a decent catch on only one night. The trick was to run the nets after the sun fully set and before the moon rose. Conditions improved through the period, but we had to close the nets…
