Birds of the Rio Grande Valley – Part 2
This week’s Blog is Part 2 of Birds of the Rio Grande Valley.
I have taken the liberty to include some information you might find interesting and thought provoking.
If you will look closely at the tree trunk the Yellow-bellied Woodpecker is clinging to, you will see a series of small holes. These were made by the woodpecker to attract insects for a food source. Sap seeps into the holes which attracts insects. I like to think of this as “Woody’s Cafeteria”.
According to the American Bird Conservancy hundreds of millions of birds die each year in collisions with man made structures, including glass windows and buildings, communication towers, and wind turbines. Surprisingly the largest contributor to bird mortality is free-roaming domestic cats. These cats kill an estimated 1.4-3.7 billion birds yearly. To gain a perspective of the enormity, consider that 1.4 billion is equivalent to the entire human population of China. The following yearly data gives you an idea of the bird mortality rate when birds collide with manmade structures:2013 Wind turbines 573,000; 2012 Towers 6.8 million; 2005 Power lines 175 million; 2014 Glass 300 million -1 billion.
The effect of free-roaming domestic cats on the bird population has become a Hot Button issue between cat lovers and the protectors of the birds.
