Probably a shitty combo of the daiichi discharge with climate change warming waters and fucking up marine ecosystems. In a healthier ecosystem the fishery mightve been more resilient but having both happen probably means the animals and plants that live there can’t handle perturbations and any small change in pollution anymore.
Professor Spencer says gynandromorphs – animals with both male and female characteristics in a species that usually have separate sexes – are important for our understanding of sex determination and sexual behaviour in birds.
The main groups in which the phenomenon has been recorded include animal species which feature strong sexual dimorphism; most often insects, especially butterflies, crustaceans, spiders, even lizards and rodents.
“This particular example of bilateral gynandromorphy – male one side and female the other – shows that, as in several other species, either side of the bird can be male or female.
“The phenomenon arises from an error during female cell division to produce an egg, followed by double-fertilization by two sperm,” he explains.
Not just may, does. It’s less species to hop to, but smaller genetic pools mean that within a species it’s more likely to spread with less immune response, or has less to mutate against.
I was really excited to try this to try and figure out what the squeaky bird hiding in a tree by my window was, but it's not picking up anything (gives a pop up about how google assist interferes, but I've never had that enabled on my phone so I can't do much else) :(
It’s a great software but is not perfect. You should try posting your recording on an online birding group. There are lots of talented birders who can identify songs and calls!
