March means baby raptors

Photo: The Raptor Center

The three photos in this post show different ages of great horned owlets. The first chicks (above) are about two-and-a-half weeks old. The second picture with the chicks near their nest tree are about three to three-and-a-half weeks old. The last photo is of a chick about five weeks old.

As the days continue to get longer, The Raptor Center at the University of Minnesota anticipates the upcoming raptor baby season.

Learn what you can do if you find a baby raptor on the ground or perched on an unusual structure.

Night owls at The Raptor Center clinic

Wrapping wiggly patients, such as this saw-whet owl, in a specially designed wrap makes it easier to weigh them.

Since the first of October this year, the University of Minnesota Raptor Center’s clinic has admitted 15 Northern saw-whet owls.  This is not unusual because the little owls typically make their winter movements during this time.  What is unusual, however, is that five of them were already banded!  We do not yet know their individual stories, but we expect to receive information from the Bird Banding Lab in the near future.

Why were these owls admitted?  The majority of them suffered traumatic injuries from colliding with objects such as windows.  Head and internal trauma were common injuries, but the bird pictured here suffered from a fractured pelvis.  This adult female saw-whet was a restless patient, but after about two weeks of cage rest and one week of exercise, her energies were once again put into surviving life in the wild.

Northern Saw-whet owls are the smallest owls in Minnesota.  They weigh in at only 65-100 grams (females are larger than males), live in woodland areas in northern and central Minnesota (some now nest in the Twin Cities area) and are cavity nesters. Their diet consists primarily of mice, the availability of which often determines the extent of their winter movements.
