In 1920, there were over 138 General Notes published in The Auk, 75% of which dealt in some way with distribution. Overall, 70% of all reports originated from east of the Mississippi. Fifteen dealt specifically with irruptions, including Bohemian Waxwings (Bombycilla garrulus), Newfoundland Crossbills (Loxia curvirostra), White-winged Crossbills (L. leucoptera), and Evening Grosbeaks (Coccothraustes vespertinus). Sixteen reports were on behavior, with authors reporting on courtship alluding to major articles featured in The Auk earlier that year. R. W. Shufeldt (1850–1934) exhibited a surprisingly compassionate nature, attributing changes in nest-site selection of House Sparrows (Passer domesticus) to persecution following their introduction in 1851 (37:582). W. L. McAtee (1883–1962) reported correlation of emergence of periodical cicada (Magicicada spp.) and declines in fruit crop damage (37:144–145). In his report, he struck on the concept of functional response, stating, “...birds almost invariably specialize on the most abundant or most easily accessible food supply.”

在1920年，The Auk上发布了138多个通则，其中75％以某种方式涉及发行。总体而言，所有报告中有70％来自密西西比州东部。有15个专门处理了骚乱，包括波希米亚连雀（Bombycilla garrulus），纽芬兰Cross（Loxia curvirostra），白翅Cross（L. leucoptera）和晚蜡嘴鸟（Coccothraustes vespertinus）。有16篇关于行为的报告，其中有作者关于求爱的报道，提到了当年早些时候The Auk的主要文章。舒菲尔德（RW Shufeldt，1850–1934年）表现出令人惊讶的同情心，这归因于麻雀的巢址选择变化（自1851年被引入以来，过客者就受到迫害（37：582）。WL McAtee（1883–1962）报告了周期性蝉（Magicicada spp。）的出现与果实农作物减产的下降之间的相关性（37：144–145）。在他的报告中，他强调了功能响应的概念，并指出：“ ...鸟类几乎总是专注于最丰富或最容易获得的食物供应。”
