Bates's pygmy antelope
Bates's pygmy antelope eat leaves, buds, shoots, fungus, grass, and herbs. They also eat crops, which makes them unpopular with farmers. They are often caught in snares near agricultural fields. They have a typical territory of . Males are territorial, marking their territory with scent produced in the preorbital glands. Females are friendlier with each other and sometimes live in small groups. They bark when fleeing. Most pygmy antelope mate at late dry and early wet seasons. Gestation period is 180 days. One young is born per pregnancy. The fawn weighs between .
San Joaquin antelope squirrel
It is omnivorous, feeding on seeds, green vegetation, insects, and dried animal matter. It occasionally caches food. Redstem fialree ("Erodium cicutarium") and brome grass ("Bromus rubens") are important food items for the squirrels. However, their diet may differ depending on the time of day or time of year. Green vegetation is the most common diet type from December to mid-April because it is the most abundant during this period. Likewise, insects make up more than 90% of the squirrel's diet from mid-April to December because they are more abundant. Although seeds are available for most of the year, it is not the preferable diet of the squirrels. They will choose insects or green vegetation when available over seeds, even if the seeds are more abundant and easier to access. Some speculate that this could be due to the higher amount of water in insects and green vegetation, which would be necessary for the species to survive in such a hot, dry climate. Unfortunately for the Nelson's antelope squirrel, there is not an abundant water source nearby. Under laboratory conditions, the squirrels readily accept water. However, they can also survive at least 7 months in the shade without water. At the end of 7 months they appeared relatively healthy and not at all emaciated.
