The Season, Spring 1971

Published in 1971

The weather continues, for 10 years now, colder than norma1. By comparison, March was warmer than April or May. For bird migration, this means more and stronger cold fronts and so more records of rarer species that usually completely overfly our state, such as many shorebirds, Black-billed Cuckoo, Wilson’s Warbler. It also means that the advance of spring, the development of vegetation, emergence of insects, and the progress of the birds inland was at least 2 weeks late. In March many birds arrived from across the Gulf about on time, but they then encountered unfavorable flying weather, and, with vegetation and insects behind schedule, the birds found it difficult to replenish their fat reserves to continue their journey.
