@Figstation I'll definitely check out the Bird Gard.
@ Darkman I agree that introduced bird species are a terrible threat to our native birds . So are other introduced flora and fauna. IDK what the answer is and I've never been able to accept the cruelty of the food chain, its bigger than I can comprehend. There are also natural events that introduce new species into environments with devastating consequences, but man does it faster. Every ship or plane has the potential for introducing new species. I'm trying to learn ways to co-exist with nature while planet Earth deals with man's folly.
I feel privileged that I witness murmuration of starlings a couple time a year, but I also anguish over the havoc they cause. I too was horrified to find a mother bluebird killed in a nest box
I believe "lazy" is a human attribute. For other life forms the path of least resistance is survival.
IMHO man hasn't done well covering his footprints, such as the slaughter of 40,000 elephants proposed to stop the desertification of Africa,but it actually accelerated it!
I just want to use humane methods to harvest fruit. I don't own the planet and I don't think mankind's knowledge is equal to our power to do harm.
