lethargic

DSC_0902 edit 2b

I had been waiting to see up close a fledgling tit-mouse and got lucky today but he seem lethargic and nobody was feeding him? All you can do is say a little prayer for these wonderful creatures.

We buried our friend under our banana trees at dusk after his last breath, a shitty way to get a photograph for me. His beak looked damaged probably from flying into something?

“Generally, it appears that the heaviest post-fledging mortality occurs among inexperienced young birds, and that for adults, after they have successfully reared young, the probability of death each year remains roughly constant. In other words, few birds die of “old age — they just run the same gamut of risks year in and year out until they are killed. The annual risk of being killed varies from about 70 percent in small temperate-zone songbirds (adult life expectancy about 10 months; in the tropics adult songbirds are thought to be much longer-lived) to 3 percent in Royal Albatrosses (fife expectancy slightly over 30 years). If a bird lasts long enough, however, the probability of it dying in a given year may once again rise.”
