1. The grey forehead and face, delimiting a green hood, give this bird its name. Native to South America and considered as one of the greatest avian plagues in Spain and other Western European countries, what bird are we talking about?
Answer: Monk parakeet
Interesting Information:The monk parakeet (Myiopsitta monachus), also known as the quaker parrot, has proved to be a very adaptable species, now ranging through most of Western Europe (especially Spain, Italy and Belgium, with a variable and almost controlled population in the UK), the Caribbean and some major cities of the United States of America. The main methods proposed for controlling the population of this parakeet include destroying their nests (by taking them to pieces, burning them or even watering them before a freezing night) and mass-sterilization.
Although also being an invasive species, the rose-ringed parakeet (Psittacula krameri) doesn't match with the description given.
The other two species, the white-cheeked turaco (Tauraco leucotis) and the brown-necked parrot (Poicephalus robustus), aren't reported from countries outside their native regions apart from eventual escapes.

14. This time we focus on a medium to large-sized waterfowl, a quite aggressive one (particularly to other waterfowl), which undoubtedly is an invasive species in NW Europe although it was initially introduced as an ornamental bird. Which one is this?
Answer: Egyptian goose

40. Since the fall migration of birds south across the Gulf of Mexico coincides with hurricane season, birds sometimes fly into hurricanes and are killed. When their bodies are washed up on shore, why is it frequently so hard to determine their species?
Answer: the waterlogged feathers often appear black
Interesting Information:The colors in the feathers of a bird are formed in two ways, from pigments and from the way light reflects off them due to the structure of the feather. Reds and yellows come from pigments. Blues are from light refraction and greens are from a combination of yellow pigment overlaying a blue reflecting feather structure. The feathers of a bird that is completely waterlogged, as one washed ashore after a storm would be, are too wet to reflect any light and so would appear black. Thus any bird that was largely green or blue (such as blue jays, Steller's jays, blue grosbeaks, or green herons) would appear black instead of blue and thus be difficult to identify.
Difficulty: Hard.
From Quiz: North American Birds
Some incorrect choices:
they are so smashed up, they are unidentifiable, their feathers have all been blown off, they have no wings
