It is not particularly big but has a reported 430 bird species including migrants, though during my short stay it seems I missed most of the key attractions among them. Poor researchers Nicola Coumi and Rob Slotow failed to find anything particularly interesting about vigilance in Bronze Mannikin groups.

Or would be, had I encountered more of them – so far, I have seen only a very small share of the approximately 233 woodpecker species, and got decent photos of an even smaller number – not much more than 10% of all of them. So, writing a post about them is easy.

Because there is no national list of birders, the survey was conducted using eBird membership in the United States, which may or may not be representative of American birders generally. In other words, the researchers sought to determine attributes important to birders, and how those attributes rank relative to each other.

This research suggests that the boom isn’t due to an influx of newcomers, but rather because more local birds are flourishing and successfully rearing families. Specifically, researchers found that in EAB-infested areas, the birds preferred ash trees to other trees, and seemed to favor the ashes with the most severe damage.

And the term is ‘non-reversed size dimorphism.’).

The results of this research paper appear in the Journal of Zoology. It is probably the case that the rapid spread of Lyme Disease from Connecticut to the rest of the United States and adjoining regions of Canada was because some species of birds (but not all) can carry Lyme disease, and can also carry the ticks that carry the disease.

They are a commensal species, meaning that they are a wild animal that lives in close association with humans, not as a pet or as a farm animal but more like a parasite, to the extent that it is hard to find them in truely wild settings, and it is hard to find human settlements without them. When a car comes along they fly away.
