Pellets from Tuas: 8. Black-shouldered Kite feeding chicks
By Chan Yoke Meng & Melinda Chan, 13th April 2015;
The ground below the nest of the Black-shouldered Kites (Elanus caeruleus) is often littered with carcases of mice and numerous pellets. The image above shows a headless mice found below the nest. An intact mouse was also found below the nest.
We believe they fell from the nest when brought in by an adult. We had observed that within minutes on the ground the dead mice would be covered with ants. Thus returning it to the nest would introduce ants and pathogens. Another reason these fallen mice were not retrieved can be that there were no shortage of mice in the area.
