Natural resource management advisory series : note 6: Raptor & water birds nest trees

Abstract

This advisory note examines the nesting characteristics and conservation requirements of raptor and colonial water bird species in North East New South Wales, Australia. The document provides detailed analysis of nest construction patterns, with raptors and waterbirds building substantial stick nests ranging from 0.4 to 2 meters in width. These structures, often used across multiple breeding seasons, are typically constructed in specific locations critical to breeding success. The study identifies key species including the endangered Red Goshawk (Erythrotriorchis radiatus) and vulnerable Osprey (Pandion haliaetus), documenting their distinct nesting preferences and breeding periods. Conservation recommendations emphasize the importance of maintaining a 50-meter protective buffer zone around nest trees and preserving surrounding vegetation essential for nest security, roosting, and perching. The document highlights the sensitivity of these birds to disturbance during breeding seasons and the potential for nest abandonment, underlining the significance of habitat protection for successful breeding outcomes. This technical guidance, published in 2004 by the NSW Department of Environment and Conservation, serves as a comprehensive resource for environmental managers and conservation practitioners in identifying and protecting critical nesting habitats for protected raptor and water bird species in eastern Australia.
