Popis:	During the breeding seasons 2001–2005 we determined the nest measurements and characteristics of a Chilean Hawk (Accipiter chilensis) pair in an Andean Nothofagus forest of northern Patagonia (36°S; 50 km east of Chillan). The five platforms were built on forked branches in the upper part of the trees, 16–20 m above ground. One nest and one nesting tree were reused. Nests were built close to the main trunk or a vertical gross branch. The nesting trees were live adult Nothofagus dombeyi trees. The measured nests were oval‐shaped platforms similar in size. Nests were built with dry twigs and sticks, which were strongly intertwined. The egg‐shell remains found under the nesting trees were light bluish white or dull white, unspotted and nonglossy on the outer surface, and bluish tinged on the inner surface. Minor differences were found between our descriptions and those previously documented, which could be due to differences in sample size, individual differences between pairs, or structure of the nesting tr...
