They are an odd group of birds. Its strange that they don't venture east where the farms are. I really don't know what they are eating to stay alive.Must be very cold tolerant parrots!! I have live in Lewellen, Nebraska (panhandle near North Platte River) and saw -50F on chilly morning I believe it was 1983. I grew up in NW Nebraska where winter temps can plummet down to -20 -30 and occasionally -40 F. Yet Wyoming, which is only a few miles from where I grew up, Quaker Parrots are illegal to own because of the chance of them getting out, breeding and making a nuisance to crops. I think they would be a LOT less worry to crops than say a flock of Startling or other birds.
Their nests are giant. I'll try to get a picture next time I'm in that neighborhood.I'll bet its warm by that light abd its wind block. Smart parrots!
I have an article in ornithology showing quakers are not crop destroyers . And are actually beneficial to native birds, as documented use of their nest structures by st least 10 native species i think. Documented not aggressive to other species when observed in mix flocks at feeders or wikd food sources
THe theory about quakers goes: They are communal nest builders, and are EXCEPTIONALLY good at building them. In populated areas they tend to build them on utility poles and especially those with electrical equipment on them like transformers which generate heat. The nests prevent the transformers from dissipating the heat and either quit working or in rare cases break out into fires.
Ever want to see how well Quakers build, throw a couple handfuls of popsicle sticks into their cage; you'll be hard pressed to take it apart.
