Species Spotlight: The Tenacious American Crow
Crows are extremely social birds, and can often be seen in large groups, most of which are family, as the young often will not breed until they are 3 or 4 years old, and help in raising their younger siblings.
With their intelligence, American Crows are adept at solving problems, and with such can often obtain food from the most unlikely sources, even being so astute as to reportedly following other adult species of birds to find their nests in order to raid the nest for eggs or babies, which shows that they are able to rise above simple problem solving skills, and to be able to plan. It has also been said that crows are able to use everyday objects as crude tools, for example if they happen to come across a shellfish such as a muscle they will fly up in the air with it, and drop it onto roadways to crack open the shell. They are also team players and will work together to solve problems, such as working in teams to chase of potential predators such as raptors that may pose a threat to them or their families.

American Crows live plenty long enough to learn these skills of survival as they can live for as long as 16 years in the wild, some reports of these birds living twice as long in captivity have been recorded. Some crows have displayed behaviors such as "collecting", where they will decorate their nests, which both the male and female will build and maintain, with shiny objects that they find.
A definate master at survival, whether is calls home open fields, woodlands, wetlands, or urban environments, this loud mouth of the bird world deserves some respect for its intelligence, its dedication to its family, and its ability to readily adapt and overcome. The American Crow, definately one of my favorite birds, which around my house we refer to them as CAW CAW birds!

And then it was gone...
That afternoon, I decided the lightign was fairly decent, so I would stop by the beaver pond on the way home to try and get some more shot of the beaver, or perhaps the bald eagle that I had spotted around there recently, if not the eagles, certainly the chances were good to get a shot or two of the Northern Harriers, or one of the three species of Herons that have come to frequent the beaver pond.
Much to my amazement, the pond was pretty much gone. A couple of utility truck and an older green dodge intrepid were parked in the area, being a good boy I went about my business.
the next morning I drove past the pond (or what was a pond 24 hours earlier), and it was bone dry with the exception of a little water running through the natural creek channel. Sitting high and dry was the beaver lodge, and surprisingly enough, there were no herons, no raptors, no deer, fox, beaver, to be seen.
All that was there was teh white box truck with the picture of a backhoe on the side and the green intrepid.
Days later, I learned through a nature photography contact that potentially the city of Clarkville was concerned about flooding, and hired a crew to destroy the beaver dam, and had asked the DNR to trap and move the beaver.
This pond is on the route of the emerging "greenway" path that connects the three cities riverfronts together, and to create a mixed use trail for users to experience the nature, and scenery of the Ohio River Shoreline. What a way to celebrate nature than to tear out one of natures most crucial habitats.
Interestingly enough, if the reports I heard are true and it was done out of flooding concerns, I find that strange, as the pond is located on the river side of a flood wall, in a natural floodplain of the Ohio River, in a very sparsely populated area.
Besides, is it not true that wetlands can absorb and dispense of excess water much faster than regular land?
Of course it is too late to fight the change, after the DNR built an overlook deck, installed a grill and picnic table, and had become a quite busy destination for nature photographers, and bird watchers from all across our area.
Of course we wont stop to mention the increase in species in the area since the beaver pond came about;
Blue Wing Teal
Great Blue Heron
Black-Crowned Night Heron
Green Heron
Great Egret
Northern Harrier
Red-Shouldered Hawk
Red-Tailed Hawk
American Kestrel
Northern Shoveler
Wood Duck
Greater Scaup
Bufflehead
Cormorants
Beaver
Red Fox
Eastern Box Turtle
Wild turkey
Grey Tree Frog
Leopard Frog
Bull Frog
American Toad
Northern Water Snake
Red-Eared Sliders
Common Snapping Turtles
Red-winged Black Birds
Just to start of what has been seen around that pond, but hey, those are just animals after all right?
Aix sponsa
As true to form for most bird species the males are much more colorful than the females. And in my humble opinion is only seconded by the mandarin duck for its beauty and grace.
But the females, what they lack in style can make up for that in craftiness. If there are no suitable nesting cavities in their area, a female wood duck is not to shy to lay her eggs in the nest of another wood duck, leaving the young to be hatched and raised by another. which is why at places like Muscatatuck it is nothing to see a mother wood duck with as many as 25 ducklings trailing along behind her.
Most of the time, the nest cavities are very close to water, but sometimes they can also be very far away from water as well. And upon hatching, when its time for the young to venture forth into the world, they start their lives by diving out of the nests (which are often high up in the tree) and falling to the ground or water below.

When most people think of ducks calling out, they think of the harsh QUACK usually associated with a mallard, but wood ducks have a soft whistle.

Woodpecker Profiles
Pileated Woodpecker
Next on the list coming in at 11 to 12.5 inches tall with a wing span of 16.5 to 20 inches, is the colorful Northern Flicker. Primarily an insectavore, the Northern Flicker can be seen "hunting for ants, beetles, and larvae of insects on the ground, and they are not at all opposed to taking butterflies and moths as well. In winter months they will eat nuts and berries. The best places to look for Northern Flickers are on the edge of woods, in feilds close to woodlands, or around wetlands.
Northern Flicker (Colaptes Auratus)
Coming in next at about 9.5 inches in height and wingspan of 13 to 16 inches is the sleek Red-Bellied Woodpecker. It distinctive black and white barring across its back and and it bright red cap, YOu can primarily find these guys in woodlands, wetlands, and neighborhoods that have a lot of trees. Red-Bellies feed, like other woodpeckers, mostly on insects, nuts and berries, but they have been known to eat small lizards and even minnows if they can catch them.
Red-Bellied Woodpecker (Melanerpes Carolinus)
Next is a Woodpecker whose status is considered near threatened, its the Red-Headed Woodpecker, a little smaller than the Red-Bellied, and more reclusive, the Red-Headed Woodpecker can easily be distinquished from the Red-Bellied by its solid red head, and solid black balck with white patches visible on its lower wings, and bright white belly. Red-Headed Woodpeckers are considered omnivores and will eat insects, eggs, baby birds, mice, and nuts and fruit. It is one of only 4 woodpeckers that are known to cover their stored food. Insects that it stores are kept alive, but are wedged into crevices in wood so tightly they can not escape. Also red-heaed woodpeckers are very territorial and will attack other birds in it territory, even go as far as to attack nests and break the eggs with it beak!
Red-Headed Woodpecker (Melanerpes erythrocephalus)
The next two species of Woodpecker here in our area would be the Hairy Woodpecker followed by the Downy Woodpecker.
Hairy Woodpeckers are 7 to 10 inches tall with a wingspan of 13 to 16 inches. The Hairy is primarily an insect eater and forages through bark to fnd the bugs that it finds tastey. They are not opposed to hanging around areas where Pileated Woodpeckers forage, and once the Pileated has done the hard work of digging open a tree, and has flown off, the Hairy woodpecker will fly in and search for insect the Pileated left behind.
Hairy Woodpecker Female (Picoides Villosus)
The Downy Woodpecker is a familiar sight to pretty much anyone who puts out suet feeders in our area. Measuring between 5.5 and 6.5 inches tall and with a wingspan of 9.5 to 11.5 inches, Downy's will readily mix in with other flocks of feeding birds, taking advantage of the idea of safety in numbers. They are also primarily insect eaters, but get about 25% of their diet from nuts, berries, and seeds., you may also find them from time to time taking a sip form a hummingbird feeder.
Downy Woodpecker (Picoides pubescens)
Lat but definately not least is more of a seasonal visitor than it is a resident of the woodpecker family to our area, its the Yellow-Bellied Sapsucker (no its not just an insult in bugs bunny cartoons) measuring between 7 and 8.5 inches tall with a wingspan of 13 to 16 inches, this sap-sucker is a winter visitor in our area. These guys are the only Woodpecker in eastern America that is totally migratory. And yes, they eat tree sap, along with insects and fruit. the will peck out a "well" in a live tree and maintain it so it fills with sugary sap to feed on.
Yellow-Bellied Sapsucker (Sphyrapicus Various)
Even with as large as some of our local species of woodpeckers can become, they can still find themselves on the dinner menus of our resident birds of prey, such as this misfortunate Northern Flicker that ended up on the wrong side of a Coopers Hawk:

How many different species of birds could I get in about 2 hours...
Carolina Wren
House Sparrow
Ring-Billed Gull
American Kestrel
Yellow-Bellied Sapsucker
Of course I omitted posting things like European Starlings, Mallards, Canada Geese, Robins, Etc. And about the only reason I posted the house sparrow is he was just that damn cute!

Things are not often what they seem....
Coupled with the fact that he exhibited rather un-raptorly behavior ( such as flying up and landing right next to a photographer, and started "calling" to the photographer) No matter how close I got to him, he would not spook or fly away, he just stared with increasing curiosity.
(of course he could have been thinking "how am I going to go about attacking and eating this big old thing")
The photos were posted and passed around trying to figure out what could be wrong with this little guy, and a few people went half insane trying to figure it out, if he was hurt, he needed to be captured and taken to a raptor rehabilitor.
But it turns out the joke was on us, and the hawk was just fine!
The protrusion in his chest, is nothing other than his right foot!!! Young Red-Shouldered Hawks will draw their foot and leg up into their warm feathers when it is very cold outside, and switch which foot is exposed to the cold air!
Now, I have seen this behavior exhibited in all manners of Cranes and Herons, ducks and geese, and of course Flamingo's (since we have such an abundance of those around here), however I had never witnessed such behavior in a raptor. I had seen them squat down in the could to cover their feet, but never do a leg lift and tuck!
So thanks to those who helped to slove this little mystery!
