Bird Surveys of the AVC Lancaster Campus 2026 –
Callyn D. Yorke, Ph.D.
2 November 2026 (17 Species)

Weather: Fair; intermittent light rain during the past two days; 53°F to 68°F; wind ENE 2 -5 mph.
Time: (PST) 0900-1109 hrs.
Area Covered: Beginning at the administration building parking lot, I used the sidewalks in the southeast corner of the campus, then crossed a mowed lawn leading to an angled walkway from 30th St. West and Avenue K. This area had a mature, fruiting olive tree and two rows of Chinese Pistache trees with abundant clusters of berries (photo); both of these fruiting ornamental trees(the pistache tree is throughout the southeast section of the campus) were highly attractive to birds.

I continued walking north then westward to the edge of the playing fields, where a row of cedar trees was checked for birds. From there I proceeded north to Champion Way and eastward, passing the abandoned garden of the horticulture center, where a dead Joshua Tree remains standing – evidently the last remnant of Western Mojave Desert native vegetation on the AVC campus.
This was my first comprehensive campus bird survey since most of the construction and landscaping was completed. It was gratifying to see that the campus is once again an attractive educational environment and that bird diversity is beginning to return to previous levels. Significantly more shelter and foraging opportunities are now available to birds than during the many years of demolition and construction. If water features are added to the campus landscaping and native Mojave Desert vegetation is planted in the horticultural yard, bird diversity and abundance levels could reach or exceed what they have been in years past (see AVC Lancaster Campus Bird List).
