Instagram Beaks are really works of selected art. They are sturdy enough to tear into flesh and hammer at nuts, but precise and delicate enough to feed nestlings or peel grapes.
And while they may look hard and unfeeling they contain a tremendous amount of nerves and are quite sensitive.
They also contain a lot of iron. Early studies suggested that those clusters of iron crystals, or magnetoreceptors, allowed birds to perceive magnetic fields, and thus correctly orient themselves.
More recent evidence though, suggests that birds might actually be able to see—literally see—magnetic fields via special proteins in their eyes called Cry4 proteins. Oh hello there. Would you like to know something interesting about me?
I have the potential to live up to 60 years old if everything goes my way. Of course in the wild, things never do and my best chances there are for a lifespan of about years. The toughest time for me is the first couple years of my life. A captive crow from NY named Tata is the current verified record holder. He lived to be 59 before he passed away in Why a white-necked crow Corvus leucognaphalus! This species is native to Hispaniola but has also been observed in Puerto Rico. Both can be eliminated due to their lack of nasal feathers and bill shape. I saw at least a few folks basing their guesses on these features so well done to you!!!
Fun fact: white-winged choughs are not corvids even though the alpine and red-billed choughs are. They are in the Corcoracidae family. That means Australia has not one but two birds named after actual corvids but who are not corvids. Bonus question: Who can name the second? Not fun fact: The white-necked crow is sadly considered declining and vulnerable and is the rarest of all Caribbean crows. This is primarily due to habitat loss and over exploitation by hunting. Thank you for playing this week!

This photo was extra tricky for two reasons: one, carrion crows are a little more robust than American crows, so North American players were at a slight disadvantage with the proportions. The second is that without the head feathers, that bill looks a lot bigger than it typically does.
Your eye is totally thrown. Both crows and ravens can get a lil hook like that. Why birds have bad molts like this is a mystery to me. But the feathers will grow back and it will should be looking good by now. Thanks for playing everyone and have a great rest of your week! When we think of the evolution, speciation, and the tree of life, we most often think of it as a linear, forking process.
Species are always marching forward, adding more branches to an ever growing tree of life. But we now understand that sometimes things march backwards, and branches can actually be reabsorbed in a process called reverse speciation. One of the best examples of this is in none other than the common raven. A robust study by Kearns et al. See, once long, long ago, perhaps on the order of 1. These groups were reproductively isolated did not hybridized and colonized different parts of North America.
From there, the California lineage diverged from the extant still living Chihuahuan raven.

Sometime after this, maybe ,, years ago, the Holarctic lineage and the California lineage found themselves in contact once again. What this means is that common ravens are actually a hybridized product of two distinct groups. Yet the same has not happened with the Chihuanhuan ravens, which remain reproductively isolated to this day, despite regular contact with common ravens.
Goes to show when we try and short animals into neat little boxes, they sometimes have the last laugh! Oh goodness me how this fills me with glee! CrowOrNo has returned to test what you've learned. I await what your answers will be! An American crow that I saw last weekend on the WA coast to be precise. So how could you tell? This one was a little tricky but you have s few clues to help you out.
The first is that you actually get a pretty good look at the bill and its proportion to the rest of the body. The second is you get a good look at the finger feathers on the right wing. Remember that crows have 5 main fingers whereas ravens have only 4. Thanks for playing everyone! I knew they were smart, especially in groups. A murder of crows. Was the person that coined the phrase stalked like this? Or was it just their dark plumage and propensity for snacking on carcasses? Whatever the case, it seemed fitting now. I was getting death threats from a murder of crows.
A Murder of Crows
Rather than feeling frightened, however, I was fascinated. These fantastic creatures and their keen eyes made dragonfly sex look dull. Whatever the game was that we were playing, it must have come to a draw. As I stopped ducking as much, the crows stopped flying so low. Eventually, they stopped flying at me altogether, and seemed content to caw at me from the trees. Here, I was already thinking of ways to lure them closer to my house, bribing them with goodies like peanuts and shiny things. Today, the crows and I have sort of a mutual acquaintance going.
The crows stop by to visit on occasion, along with blue jays and squirrels. Nice account and video, Karmen! I've had this happen to me as well. I suspect that you were near a nest-tree, and that crows which persecuted you were a family flock made up of a mother and her grown progeny.
