North America's Migrating Monarch Butterfly is Now on The Endangered Species List


Monarch Butterfly added to Endangered Species List by IUCN


The migrating Monarch butterfly, the North American subspecies, was declared endangered on July 21, 2022 by the International Union for the Conservation of Nature (IUCN).  This subspecies of the Monarch butterfly is known for its twice yearly 2,500 mile journey between its summer and winter areas.  


There are two North American populations; the western population (west of the Rockies) and the eastern population (east of the Rockies).  Although more is known about the eastern population, both have suffered dramatic declines in recent years; the western population has lost 99% of its members, declining from about 10 million individuals to about 250,000.  The eastern population has declined about 84% from 1996 to 2014.

The major threats to Monarch butterflies are habitat destruction, especially in the wintering areas and pesticide use, primarily in the Midwest where glyphosate severely impacts the milkweed on which the Monarch depends. These threats are still of concern despite successful programs that have established monitoring and important way stations where milkweeds and other native plants have been established along the migratory route. 


The listing was announced because the threats to the Monarch populations are greater than current conservation efforts and it is hoped that by listing the Monarch as endangered it will stimulate additional conservation efforts.

Window Bird Collisions


Guide to Bird Window Collision Prevention

More than 100 million birds die each year hitting windows of residential homes.  After cat predation, window strikes are the leading cause of avoidable bird deaths.  If you were curious how to go about preventing window strikes in your home, then Jim Cubie's "Consumer Guide to Bird Window Collision Prevention", may be worth a look (click here to download).

The guide describes proven options for prevention, how to make a DIY version of each option, a comparison and costs of each option described.  All options discussed in the guide are approved by the American Bird Conservancy.

The free, 27 pages guide includes photos comparing windows with and without the prevention system installed.  The comparison looks at effectiveness, durability and ease of installation of each system.  You can also download a video version of the guide here.
