Sometime in the 1990s, a mutant crayfish able to conquer and degrade aquatic systems emerged as a result of secret German experiments gone awry. The marmorkreb, a.k.a. marbled crayfish (Procambarus virginalis), is a destructive new species that first appeared aquariums in Germany. However, it’s more likely the result of too much inbreeding in captivity, rather than some mad-scientist scheme, that led to their mutation. They are now here, and your help scouting for them is invaluable.

Describing happiness attracts animals: Apparently, we can have a whale of a time, be as pleased as a pig in a peach orchard, or feel as happy as a pup with two tails, a monkey with a peanut machine, and a clam at high tide. Given all this, it’s natural to wonder if non-human animals can feel happy.
Many biologists caution against ascribing human-like emotions to animals. This is a hilarious warning, because we are after all a species of animal. Gauging critter-happiness is a challenge, but it’s easy to tell when animals are miserable. Cortisol, a steroid hormone produced by vertebrates in their adrenal glands in response to stress, can be measured in saliva or blood.
So we can tell if a deer, goat, or cow feels stress rather than bothering with surveys, which were only ever returned by dogs anyway, and even then they were drool-covered and blank. Aside from basic requirement like food, water, exercise, and adequate protection from weather, most animal species have an intensely strong need for social bonding.
Happiness may be elusive, but it has sure spawned a lot of aphorisms and similes. Folk-wisdom indicates one can be happy as a pig in poop – or in mud, which makes me wonder if those two hogs are equally content, and if they had other options. It also suggests you can have a whale of a time, and be pleased as a pig in a peach orchard, which would make sense unless harvest season was over. Additionally, one might feel happy as a pup with two tails, a monkey with a peanut machine, or a clam at high tide.
When the topic of animal intelligence comes up, we might argue whether a crow or a parrot is the cleverer, or if dolphins are smarter than manatees. Seldom do we ascribe smarts to life-forms such as insects, plants or fungi. And it is rare indeed that we question our intellectual primacy among animals. It is true that no other species can point to monumental achievements such as the Coliseum, acid rain, nerve gas and atomic weapons. But that does not mean other species are bird-brained. Metaphorically speaking.
When we hear the term “Snow Birds,” we naturally think of a person who migrates from the colder northern parts of North America to warmer southern locales but birds here in the Adirondacks also claim this title and fittingly so.
As winter approaches the mountains, an entire orchestra of song birds migrates to a warmer, southern winter territory. The morning music of feathered chirpers throughout the spring and summer months have flown away not to return until April-May next year.
These flying migrators range from 29 species of warblers to various populations for thrushes, sparrows, flickers, bluebirds, buntings, sapsuckers, wrens and hummingbirds. This does not leave winter void of the sound of winged music, there are songbirds that remain and brave the cold.
