The local Bald Eagles are getting busy, I suspect there is an egg in the nest. The birds were too far away to identify, and I know more than one species does this, but if I had to guess they were starlings. If half the Warblers go extinct, that would be a lot of species but you’d still pretty much have Warbler DNA.

We can, of course, count wild, native, species. We can count vagrant species that made it to the area we are in under their own power. We can count introduced species that have met the criteria of the “Bird Police” for the area to which they are introduced. When we eat eggs we eat chicken eggs almost exclusively.

Peripatetic ornithologist Nick Sly has long been a friend of the blog here and has contributed such classics as Green-rumped Parrotlets from Egg to Adult and Forpus passerinus and the Ornithologists of Masaguaral. This kind of detailed genetic and developmental work has traditionally relied on model species in the lab (aka chickens).

Interestingly, these juveniles look more similar to another species, the Pale-billed Parrotbill, than the adult babblers – and they sometimes are part of the same flock. Then we are both hopeless … Anyway, the paper tests whether small roads in a forest are a hindrance to birds – are they reluctant to cross?

Both Elk and songbirds have the same basic method of inseminating eggs, which is one of the steps in reproduction (but not by any means the first!), Songbirds grow the offspring internally for only a very short while, and then pop out an egg, which is then cared for over a significant period of time until it hatches.

The vast majority of the 10,000+ living species of birds are passerines, and the vast majority of those have a similar system of breeding: Mom and dad bird make a nest and share parental responsibilities roughly equally, if not identically. There are variations on that theme, of course. Even the non-passerines often follow this pattern.

Their habitats vary widely in both rural and urban landscapes; open habitats are preferred and the species generally shuns only extensively forested areas and wetlands 1. To show how adaptive this species is, the following photograph was sent to me by one of my readers and I use it with her permission.
