> Findings show there are about six birds per human being on the planet
Have you fed your six birds today?
> there are 50 billion individual wild birds and more than 9,700 different bird species in the world
> Birds of the so called “one billion club” are the house sparrow, European starling, ring-billed gull, and barn swallow.
What’s a ring-billed gull? It isn’t even on my charts of the most widespread birds of the world. Only North America.
> To find out if they are increasing or decreasing is really important
Which reminds me. I hope the detailed results from the ABBC Australian Backyards Bird Survey from last October are ready.
No link to them. Seven months and still no results!

Well most species are decreasing, even the ferals. Many are relocating to where they have never been recorded before. I’m reasonably sure that points to something rather important to notice.
