As one of the best-known bird painters of the twentieth century, Allan Brooks is a familiar name to most birders. Before his art was more widely recognized, Brooks devoted much of his time and owed much of his income to securing and preparing Canadian birds and mammals for collectors in the US and England. Summer of 1901 found him far to the northwest of his Okanagan Landing home, working in the Cariboo. From a base at 158-Mile House, Brooks made collecting excursions throughout the Horsefly area, including to nearby Carpenter Mountain.
Tennessee warblers arrived there May 22 of that year, and by June 15, “a good many” singing males were present in the area. That day, while Brooks “suffered torments from the mosquitoes,” he followed a female to her nest, whence he “put her off and shot her … as she fluttered off.” Over the next week, he found several more nests, some with eggs and some with nestlings; it is unclear whether he collected the little chicks, but he did take the nests with eggs, which “contained small embryos.” (Auk, January 1902) By 1905, one set, shown in the photo above (Oologist, September 1905), entered the cabinets of J. Parker Norris, Jr., in Philadelphia, joining “an unparalleled long series of wood warbler eggs [that] alone occupied more than an entire large cabinet” (Kiff, “History of the WFVZ,” 2000).
As Kiff tells us, fully half of that enormous oological collection, including most of the North American eggs, passed after Norris’s death into the hands of Nelson Hoy. Over a long life, this Pennsylvania collector amassed some 15,030 sets of eggs (Kiff, “Bird Egg Collections,” Auk 1979), making it the largest such collection privately held in North America.
I do not know whether that collection, which absorbed many others in the twilight period of American oology, was accessible to researchers during Hoy’s lifetime, but he “entertained scout groups and school groups on an almost daily basis” in his private museum in suburban Philadelphia. A year after Hoy’s death in 1979, the nests and eggs—which “more than filled a 42-foot trailer truck“—were moved to the Western Foundation of Vertebrate Zoology, where they remain today.
