But while humans mainly try to stay slim and fit for health reasons, Eurasian Siskins care more about the danger of being eaten. In science speak, this is named the optimal body mass hypothesis. Eurasian Tree Sparrows frequently find themselves out in the wild without a glass to drink from.

Over the next few days, I found increasing numbers, goldfinches, juncos, white-throated sparrows. Dead birds are a part of the life of a birder, a feeder of birds, and of bird science. I was shocked when I found the first body, a female Towhee. I hoped it was an anomaly. Were they always there and I just never noticed?

In the slightly frighteningly named journal “Science of The Total Environment”, there is a paper on organochlorine compounds in Purple Heron eggs nesting in sites located around a chloralkali plant (Ebro River). More work, less fun, all because humans introduced some stupid fish into kingfisher habitat.

It seems the ones I got decent photos of are all juveniles – it generally seems to be easier to get photos of juveniles as they have not quite learned to avoid humans. And yes, sparrows in areas with polluted air are less healthy. Thank god that this does not apply to humans. Not this one though.

”* And then, my bird club friends started talking about alternate warbler songs and sparrow dialects and I thought, “Really? And, that sparrow I heard in California that sounded so different really is a Song Sparrow?” Bird communication is a complex and evolving science. There is so much here!
