The State Department of Agriculture introduced Cattle egrets to Hawai'i in 1959 in order to control fly populations that were harassing cattle herds. But like the non-native Barn owl, the Cattle egret's introduction has had some unintended consequences for native bird species. Special thanks to the Macaulay Library at the Cornell Lab of Ornithology for use of their field recordings in today's Manu Minute.

Manu Minute: Cattle egret, the elegant invader

Need a break in your day? Whether you're in your car or still in bed, Manu Minute brings you rich sounds from Hawai'i's native forests and shorelines. Each week, we feature a different Hawaiʻi bird and its unique song, and talk about its environment and conservation.

Manu Minute is a collaboration between HPR and the LOHE Bioacoustics Lab at the University of Hawaiʻi at Hilo. It is hosted by Patrick Hart, the lab's principal investigator, and produced by HPR's Savannah Harriman-Pote and UH Hilo's Ann Tanimoto-Johnson.
