| Happy Earth Day! |
Hello friends. Today is the thirty-fifth day that I have been on leave from my work site due to the coronavirus (COVID-19) pandemic.
Happy Earth Day.
The bad news: 2.9 billion birds have disappeared over the last 50 years.
The good news: Thanks to conservation efforts, North American duck and geese populations have grown by fifty-six percent since 1970.
Birds are an 'indicator species' meaning because they are diurnal and found almost everywhere in the world in almost every habitat, they are easily observed and studied.
In general, the presence, absence or abundance of an indicator species reflects environmental conditions and can signal a change in the biological condition of a particular ecosystem. This helps scientists diagnose the health of an ecosystem. In particular, the presence and behavior of birds act as an early warning system for pressing concerns such as climate change because they have the ability to relocate to more favorable conditions.
In other words, humans need birds more than birds need humans. Birds control pests, pollinate plants, scavenge, spread seeds, transform landscapes, keep coral reefs alive, and inspire scientists like Darwin.
What better time to celebrate birds than Earth Day?
Thanks for looking and I hope all is well with you.
