The Northern Harrier is the bird of many names. It is the Marsh Hawk which cruises low over marshes and fields. It is the Hen Harrier, as it is called in Europe and Asia, presumably because it made off with a hen every now and then.

American Kestrel
If you see a small, long-winged bird hovering over an open field, most of the time it will be an American Kestrel. This type of hunting pattern is used by only a few species of birds and it is a trademark for a kestrel, which hovers by facing into the wind, flapping its wings and spreading its tail.

The Northern Pygmy-Owl (NOPO) is about 6.75” long with a wingspan of 12” and weight is 2.5 oz (70g). The genus name, Glaucidium (glaw-SID-ih-um), is shared with the Ferruginous Pygmy-Owl and is Latin from the Greek glaux, diminutive of glaukidion, meaning a kind of owl, so-called from its glaring eyes.
