BIRDS OF NEW MEXICO 
on October 11, four were seen eating Forsteria berries, a few miles 
north of Reserve; on October 14, others were found in the San Francisco 
canyon, where there were wild grapes and an abundance and great 
variety of winter bird food. Quite a number were seen from 8,500 
to 9,000 feet in the Mogollon Mountains before a two days’ snowstorm— 
October 21 and 22—and others were seen between October 27 and 30 
at the same altitudes after the weather had cleared and moderated. 
On our way out of the mountains, on October 31, we saw them at 
7,200 feet on the south side of the Mogollon grade. In 1908, late in 
October, several were seen by Mr. Bailey at San Rafael, along the 
edge of the junipers, where they were probably feasting on the ripe, 
sweet berries of the soft-leafed cedar, Juniperus scopulorum. 
At Fruitland, where Mr. Birdseye found them very common, 
October 15-November 4, 1908, they were seen in apple orchards, 
where they were apparently eating the dried and rotten fruit. Although 
he was told that they did a little damage to cherries and berries in 
their season, only a comparatively small quantity of the fruit was 
raised there. In the same year, Major Goldman saw a number of 
Robins at 6,500 feet in the Burro Mountains late in September, feeding 
on wild cherries, wild grapes, and the ripening fruit of the woodbine. 
Near Twining, late in the fall, Mr. Surber found the birds common, 
ranging from 11,000 feet to timberline. Here the storms apparently 
did not affect the hardy Robins, for they did not move up and down 
the mountains with changes in weather. 
In 1909, Major Goldman found them one of the more abundant 
birds of the middle parts of the Zuni Mountains, a few being seen on 
the higher slopes. “One shot in a meadow the middle of June, 1909, 
had its stomach filled with fragments of grasshoppers and held one, 
just caught, in its bill. Several were seen in the higher part of the 
San Mateo Mountains and one or more were noted nearly every day 
in the pinyon belt. On September 22, one in the pinyon belt was 
observed pecking at a black caterpillar, of a species that was abundant 
in places on trunks of pinyon trees and on small shrubs and herbaceous 
vegetation, and that was eating the leaves of Lycium torreyi. On 
being shot, the bird’s stomach was found entirely filled with these 
black caterpillars. 
In the Organ Mountains, Professor Merrill reports, the Robins are 
resident, breeding at 6,500 feet and higher, in July. In winter they 
congregate in the canyons at lower altitudes, and occasionally though 
rarely one gets into the valley. 
The history of the seasonal movements of the Western Robin 
given by Grinnell and Storer is an interesting one. After the young 
are grown, family parties are to be seen for a while but “as soon as the 
young are capable of getting their living independently, they gather
