White-faced Ibis

Bear Lake National Wildlife Refuge in southeast Idaho is home to about 5000 white-faced ibis in the spring.  The birds breed in colonies in the bulrushes, and the refuge has one of the largest nesting colonies.

Just outside the refuge I came across lots of birds flying in and landing in the deep grass of a hay field.  They eat aquatic insects, earthworms, larvae, and so on, and often find food in damp soil.  I’m not sure why they were gathering in this field.

It was fun watching them glide in and disappear after they landed.  They just kept coming, and every once in awhile a few would poke their heads up to see what I was doing.

I have no idea how many were hiding there, but they tend to congregate in huge colonies.  I was lucky to be able to watch these interesting birds.
