Crimsons charting course to the top

Bad news for all those fed up with endless images of Crimson Finches from Tyto. You're in danger of finch flood from Townsville Common.

But it's not my fault. Deep research (10 minutes on ebird) this morning reveals the Crimsons are taking over. From none (yes, none) listed in 2009, Crimsons now rank more or less equal with Double-barreds in sighting frequency and numbers. Left trailing, Chestnut-Breasted Mannikin and Scaly-breasted Munia (Nutmeg Mannikin), which just five years ago ruled with Double-barreds.

What's more (or maybe less, who knows?), Crimsons like water, and Townsville's been particularly dry for 5-6 years.

But so as not to be accused of speciesism, here's the other finch frontrunner.

Can DBs keep up with competition? I suspect they're slightly less adaptable. So, my money's on the Crimsons if the conditions that have brought about the dramatic change in their numbers, whatever they may be, continue. They'll outbreed the others.

Who could get tired of Crimson Finches? Double-barred Finches are no less impressive. Since weather conditions fluctuate constantly, back and forth over time like a pendulum, bird distribution and abundance follows along. Enjoy what you have until it changes. Great photos of great little birds.

Pendulum? I think more of a dangling rope with mad monkeys swinging on it. Much is chaotic and boundaries are barely discernible. The naked ape and the mad monkeys. It's good to be alive!
