No one knows when exactly this practice started or how long it took for the birds to switch from wild nesters to those that nest in manmade habitats. Over the years total reliance on humans became entwined with where they nested. While this practice benefitted farmers who now had a natural pest remover, it took away the birds ability to find habitat on their own.
I bet you didn’t know that Purple Martins were in trouble and in
need of our help to save them from extinction. Like most people, I
had no idea about their lifecycle and how it centered on successful
interactions with humans. Despite being around for millions of
years, over time things drastically changed when they went from wild
nesters to those that are dependent on humans for their very
survival.
I had the pleasure of meeting with Shelly Rozenberg who’s been
working tirelessly at saving these birds for many years as the
Purple Martin Conservation Coordinator for Audubon Everglades in
Florida. The program involves setting up nesting houses, monitoring
them when they arrive for breeding season and keeping a record of
how many eggs are laid, how many chicks hatch, fledge or die. All
this data helps to show whether a population is declining,
increasing or stable. The data is collected without disturbing the
birds by opening a small window on the side to look inside.
A little bird history
Thousands of years ago indigenous people observed how Purple Martins consumed many insects that damaged their crops. They began to hollow out gourds and put them out hoping to attract them. No one knows when exactly this practice started or how long it took for the birds to switch from wild nesters to those that nest in manmade habitats.
Over the years total reliance on humans became entwined with where they nested. While this practice benefitted farmers who now had a natural pest remover, it took away the birds ability to find habitat on their own. As secondary cavity nesters they don’t dig out their own nest, instead they reuse abandoned cavities made by woodpeckers, squirrels or owls. They also return to the same nesting site every year.
