Meanwhile, the California Gold Rush opened up yet another front in the Hawaiian migrant experience. Eighteen-year-old Henry Nahoa wrote a letter home from California’s Sierra Nevada mountains in the 1850s to express his “aloha me ka waimaka [aloha with tears]” to family members in Hawaiʻi. Nahoa’s tears were not alone. At least one thousand Hawaiians migrated to California in the period before, during, and after the Gold Rush. Chapter five explores workers’ experiences in Alta California from the 1830s to the 1870s. During this time, men like Nahoa lived and labored under Spanish, Mexican, and U.S. rule. They worked in sea otter hunting, cattle hide skinning, gold mining, and urban and agricultural work, from the coasts, to the sierras, to cities and farms. Nineteenth-century California was an integral part of the “Hawaiian Pacific World.”

Optimal foraging theory attempts to explain the foraging patterns observed in animals, including their choice of particular food items and foraging locations. We describe three experiments designed to test hypotheses about food choice and foraging habitat preference using bird feeders. These experiments can be used alone or in combination and can also provide a foundation for students to develop extensions incorporating the basic methodology. We see these experiments as most applicable in secondary and postsecondary education, but they could be adapted for a variety of educational environments and for students with a variety of backgrounds.

The foraging behaviour of captive colonies of the Damaraland mole-rat, Cryptomys damarensis, was investigated in an artificial soil-filled burrow system provided with three tray patches that varied in bulb and corm (i.e., geophyte) density and size. Members of two founder colonies (comprising three and four mole-rats) were exposed to resource patches that varied in food profitability (both size and density of geophytes). There was no preference for excavating any of the patches with different densities or sizes of geophytes. The larger geophytes were preferentially stored and the smaller ones preferentially eaten both on encounter and within the food store. The duration of handling and rate of consumption of geophytes by 15 animals of various body sizes from three colonies were recorded. Handling time was related to the size of the geophytes. Small geophytes were less profitable to consume. It was concluded that the mole-rats generally followed the qualitative predictions of optimal foraging theory but fell short of being energy maximizers.
