Baltimore Oriole (ICTERUS GALBULA) 1950 edition Audubon print, with commentary on the reverse by Roger Tory Peterson. Printed in the USA, slightly larger than 9"x11". Rescued from a church bazaar, the pages have a slight yellow patina to them, to be expected after 60 years.
"As if following some invioble schedule orioles make their annual pilgrimage over tropical jumgles, across or around the Gulf of Mexico, through the plantations of the Gulf states and ever northward until in early May they reach the elm-shaded towns of the Great Lakes and New England. A few continue into southern Canada. Bad weather might hold them up a little, but not much, and they arrive within a day or two of the same date from year to year."
