The conservation value of secondary forests for tropical nocturnal bird species.

The article presents a commentary to the paper "Old Growth (OG) and Secondary Forest (SF) Site Occupancy by Nocturnal Birds in a Neotropical Landscape," by M. Sberze, M. Cohn-Haft and G. Ferraz. According to the author, the perceived conservation value of SF is due to the fact that most old growth forests will be lost and the rapid increase in SF area throughout the tropics. The study investigated the occurrence of three pairs of nocturnal bird species within OG and SF sites near Manuas, Brazil and examined assumptions about habitat preference.
