For the arrival of Spring, a “bird card” from the National Audubon Society.

Both the National Audubon Society and regional or state societies published illustrations of birds on collectible cards.

The cards contained essential information about the appearance, range, and migration patterns of each bird.

In 1929, The National Audubon Society began offering collections of 50 cards related to specific regions of the country.

This illustration of the Black-Throated Green Warbler was from the set, “Spring Birds of Eastern North America”.

Due to climate change, the range of many birds has shifted northward since 1929.

(I do not know if the black-throated green warbler is still found in northern New Jersey and Long Island.)

One can see the black-throated green warbler in the forests of Appalachia, New England, and the upper Midwest.

These plucky little birds winter in southern Florida, the West Indies, and the Yucatán (they have been found as far south as Ecuador!) before flying north to forested areas of the US and Canada in the Spring.

They are voracious consumers of insects and caterpillars.

I love the work of the Audubon Society in promoting knowledge and awareness of birds, and in conserving bird habitats.

This postcard was not mailed; it is likely that the postcard belonged to one of the thousands of young people who avidly collected the Audubon bird cards.

The work of protecting birds is essential.

In one decade of the 21st century, migration of songbirds decreased by almost 25 per cent.

Long live the forests and the birds!
