Not only are they cute, but they're demonstrating a remarkable eating habit. Santa Monica Bay 探花精选 Society's Chuck Almdale posted this description of the photographs:
Kestrel Team Leader, Don McCartney, provided the following comment on Kestrel chick meals, which sheds light on some of the pictures.
We have documented some of the rather amazing eating habits of nestling Kestrels. One photo, taken in Wisconsin in 2005, shows an approximately 18-day old female slooowly devouring a snake. Another photo shows a little glutton on the Crooked River Ranch, who was being retrieved for banding from its nestbox by volunteer Marilynne Keyser. Several photos show close-ups of the bird as it devours a western fence lizard. It鈥檚 too bad that we didn鈥檛 have the time to check on the progress of the nestling/lizard situation a day or two later.How do they do this? Once the chicks reach a certain size, the adults drop the intact reptile in the box rather than tearing them to pieces. Specialized mouth parts, including the median ridge, keep the prey progressing inward while allowing the nestling to breathe. It is very often interesting to check the remains of prey in the boxes to discover the animals on which the Kestrels have been dining.

While kestrels aren't endangered, they are declining in parts of their range. However, they take well to nest boxes, according to the . For a PDF file that details how to build a nest box for American kestrels,
