The area in central Canada between Type 1 and Type 3 is filled with question marks. The Evening Grosbeak has one of the more interesting past and present stories of any species in North America. Most irruptive and widespread type in the West, and quite likely the most abundant too, often irrupting to foothills areas throughout much of the West. 2020 FINCH RESEARCH NETWORK, Dedicated to the study and conservation of finches and their habitats globally, Note the sharp drop in pitch and greater force in the lower frequencies. Female/immature male. One facet of my research on the Evening Grosbeak that I aim to strengthen is my survey of exactly where the different flight call types occur and where they co-occur. REPORTING YOUR EVENING GROSBEAKS Lives of North American Birds. Evening Grosbeaks tend to eat seeds of maples, ashes, apples, box elder, cherries, Russian olive, and occasionally pines (Gillihan and Byers 2001).
