FIELD OBSERVATIONS

A Western Chipping Sparrow (No.-H76614) was banded at the McKee residence on the South Rim of Grand Canyon on June 4, 1933. It reappeared at the same place on the eleventh of September and then this spring (March 29, 1934) was found there again.

Results of the early spring this year are seen in the following two reports. On April 16, Mrs J. P. Brooks noted a female Abert Squirrel near her residence that apparently had just been nursing young. On April 18, the C. C. C. telephone crew found a Pigmy Nuthatch with a nest in a tree near the Yavapai road.

**********

Three native American Pronghorn Antelope were seen at Buggeln Hill, South Rim, on April 12. They were very wild and loped off through the sagebrush toward the Canyon rim.

A specimen of Western Goshawk (female), one of the most destructive of American hawks, was collected on April 14 while in the act of carrying off a chicken from the Berry Ranch which borders on the south boundary of Grand Canyon National Park. This species has been recorded numerous times from around Jacob's Lake in the Kaibab Forest, where it was found nesting in 1931. Apparently this is the first definite record of it from the South Rim area, although H. S. and W. W. Swarth reported the Eastern Goshawk on December 18, 1929. "An adult bird seen at close range, at the rim of the Canyon near Hermit's Rest trail".

The White-throated Swift was seen darting about Grand View Point in Grand Canyon on March 25, this year. This is a full week ahead of the earliest previous date on record of the arrival of this species, April 4, 1932.

A shark's tooth was found embedded in sandstone of the Kaibab formation below Desert View Point in March. The specimen was referred to Dr. L. Hussakof of the American Museum of Natural History who kindly identified it. He writes - "The specimen is Deltodus mercurii, Newberry, 1876."

"The form of the shark of this and related genera (family Cochliodontidae) is not yet known. We know only the crushing dental plates, which as a rule are found singly. Your specimen lacks the front third; it is from the right side of the lower jaw." (see sketch) Dental plates of this shark have previously been found in the Coal Measures at Santa Fe, New Mexico, and in the Embar formation of Wyoming.

**********

A squadron of about twenty five White Pelicans (Pelecanus erythrorhynchos) was seen flying with labored beat across a meadow south of Kanab, Utah, on April 9. Although well beyond the park boundaries, it is thought that the proximity of these birds to it makes the record of sufficient interest to warrant mention here.

**********

"A yellow-headed Blackbird was seen in company with five Brewer's Blackbirds at the Grand Canyon Airport for several days, April 18 - 20." There are very few records of this species from in or near the park.
