Crow on an ice floe

Crows (Corvus brachyrhynchos) like to ride the ice floes down the Wabash River. Three other crows flew off of this ice floe before I could get this picture of the last fourth crow. A few years ago I noticed the seagulls riding the ice floes on a bitter cold day. The crows picked another ice floe and raced the seagulls down the river. The crows made noise about it. Caw! Caw! The seagulls didn't say anything. I don't know who won the race.

This crow on the ice is just north of the Harrison Bridge on the Wabash River. Picture taken January 16, 2011.

Seagulls on the Wabash are usually herring gulls (Larus argentatus). Sometimes they could be ring-billed gulls (Larus delawarensis). Haven't seen too many seagulls around lately.

More Red-tailed hawk pictures

These red-tailed hawks posed nicely for the camera. This hawk sits in an ash tree (Fraxinus) in front of the Old Chemistry Building on the Purdue campus.

A view of the same hawk in the ash tree and another red-tailed hawk perched on the roof of the Chemistry Building. Pictures taken January 8, 2011.

Red-tailed Hawk

A red-tailed hawk (Buteo jamaicensis) perches on a river birch tree (Betula nigra) at John Purdue's grave on the Purdue campus. The red-tailed hawk feeds on rodents and graduate students. This is simply nature's way of thinning out the weak and unfit grad students.

Persimmon tree bark

Persimmon tree bark has a characteristic squarish blocky look to it. This is a good example. This persimmon tree (Diospyros virginiana) is one of the trees on the Purdue tree trail on the Purdue campus. Notice the ripe fruits over the ground. This tree is in front of Grissom Hall at Grant & North Streets.

The squirrels have been using the fork of this tree as a place to feed on the ripe persimmons. Pictures taken December 31, 2010.
