It is American Woodcock, Scolopax minor.
Superbly camouflaged against the leaf litter, the brown-mottled American Woodcock walks slowly along the forest floor, probing the soil with its long bill in search of earthworms. Unlike its coastal relatives, this plump little shorebird lives in young forests and shrubby old fields across eastern North America. ...
Birds are both flying dinosaurs and flying reptiles. Yes, that's potentially confusing.
To understand the apparent contradiction, you have to understand how modern classification of organisms works (phylogenetic systematics). Under the old (Linnean) classification system, Reptilia (reptiles) was an order and Aves (birds) was a separate order. Phylogenetic ...
According to Cornell's All About Birds website, you will have to wait about a month for the nest to be cleared.
The egg incubation period is 12–14 days.
Following hatching, the nestlings will remain in the nest for another 13 days (i.e., the "nestling period" is 13 days).
However, there are two caveats to this:
A typical robin clutch size (i.e. the # of ...
I've found whatbird.com to be pretty good for identifying American birds. Asking it for grey and brown medium-sized birds that are commonly found in Texas gives 14 options, of which the best match is the American woodcock, as suggested by Sanjukta (which is conveniently early on the alphabetical list!)
They have mental maps of landmarks, which they use as well as "compass" cues:
... experienced birds can accurately complete their memorized routes by using landmarks alone. Nevertheless, we also find that route following is often consistently offset in the expected compass direction, faithfully reproducing the shape of the track, but in parallel.

This answer offers an introduction to phylogeny on the case study of dinosaurs and birds. If you are not at ease with the concept of monophyletic group, you should definitely have started with this introduction.
This post is somewhat related.
Origin of your misunderstanding
The question is all about nomenclature (and a ...
This looks a lot like a double-barred finch (Taeniopygia bichenovii). Your note about this being an "owl-like" bird is supported by it's less common name, the "owl finch", so named for the dark ring around the face.

Birds may indeed digest seeds under conditions of rest. It has been postulated that almost all current knowledge on mechanisms of internal seed dispersal has been obtained from experiments with resting animals.
A study with the mallard Anas platyrhynchos (common wild duck), claimed to be quantitatively one of the most important seed dispersing animals in ...
It's definitely a bird pelvis (synsacrum). Based on the size (~30 cm), it came from a very large bird. Unfortunately, comparative images of bird pelves are rare on the internet. Some possibilities (large birds of Sweden possibly found on the coast):

The joint you are thinking of is not a knee, nor is it an elbow, instead it is an ankle which is bending the same way as us humans. You can see from the below diagram that the knee - the joint between the femur and tibia - is just further up the leg normally hidden by feathers.
Birds have a comparatively elongated metatarsus which gives the impression that ...
In addition to kmm's excellent answer, I'd like to present the xkcd point of view.
By any reasonable definition, T. Rex is more closely related to sparrows than to Stegosaurus.

Birds have a body part known as the nicitating membrane otherwise known as the "third eyelid". This part has become vestigial in humans, where it remains as the plica semilunaris.
This image of a masked lapwing clearly shows its nicitating membrane in action, where it covers the eye in a horizontal motion. This is analogous to blinking in humans, and the ...

Birds emit infrared.
Objects with a temperature higher than the background emit detectable infrared (IR). Endothermic (warmblooded) animals keep their body temperatures at around 37oC and given the relatively cool temperatures at the earth's surface, endotherms generally emit more IR than the background. Endothermic animals include ...
Probably a domestic hybrid of a mallard.
If your duck has large patches of white where you didn’t expect it, think domestic duck.
Mallards (Anas platyrhynchos), which have the identifiable green head in the wild, are only 1 of 2 species of ducks that have been domesticated. So it would be no surprise if a strange looking mallard was in fact, ...
I just weighed a pigeon tail feather (~10 cm) long. The mass was 0.05 g. Although all tail feathers are not equal in length (and all pigeons are not equal in size), this is probably a good approximation.
Measuring the drag coefficient is going to be very challenging, because it will vary with the orientation of the oncoming airflow. A feather falling with ...
We really don't know - we can't really ask the chicken. At least, it's unlikely it's as painful as it can be with humans.
The reason human birth is (or can be) very painful is that the human baby's head has to fit through the woman's pelvis. Since splitting from chimpanzees, human heads have gotten bigger, while the pelvis has gotten more narrow due to ...
That bird is commonly called a magpie. The only species found in Alberta is Pica hudsonia. You can see a reference image on the left and their distribution throughout Canada on the right:
Interestingly, it is one of the only non-mammals studied that is able to recognize itself in a mirror. In fact, these and other corvids are thought to be some of ...
This looks pretty much like a female zebra finch to me (the male have a more prominent feather pattern). See this picture:
These birds are not native in Europe, this is correct. But it is always possible that birds escape captivity (or are released) and the live in countries where they originally not belong. I think this is the case with the zebra finch ...
It is a Red-shouldered Hawk (Buteo lineatus).
Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico.
Presence of dark wings with white spots.
Presence of dark-brownish head, orangish-brown chest.
It is a specialized feather called "down" (like in down pillows, etc.)
Down feathers have a rachis that is shorter than their longest barb. They are completely plumulaceous and have a fluffy appearance, which results from filamentous, noninterlocking barbules.
Anatomy, Clinical Presentation, and Diagnostic Approach to Feather-Picking Pet Birds
It's clearly a magpie, a member of the crow family (Corvidae). There are many magpie species throughout the world, but since you say it's native to Canada, it must be the black-billed magpie (Pica hudsonia). There are only two magpie species native to Northern America, the other being the yellow-billed magpie (Pica nuttalli), occuring in California.
I looked up winglets so I had context for this answer. I'm interpreting winglets as the vertical tips at the end of airplane wings. If so, then you are correct. The spread primary feathers of soaring birds like eagles function as winglets (Tucker 1993). Airbus has a biomimicry web page devoted to some of the biological designs, including winglets, they ...
It is White breasted Kingfisher also called White throated Kingfisher. Halcyon smyrnensis.
Why this is Halcyon smyrnensis?
Halcyon kingfishers are mostly large kingfishers with heavy bills.

Out of all the 11 species only two are ...
I'd say you guessed correctly. This does appear to be the hooded crow (Corvus cornix).
In German, it's called Nebelkrähe (meaning "mist crow").

This is a Cattle Egret (Bubulcus ibis), which is a heron in its breeding plumage. When not breeding, the bird is white. See the images for comparision:

It's an anhinga, as@kmm commented. There's nothing wrong with it; it's not deformed in any visible (to me) way. They spread their wings to dry, as they are darting birds that do not float on the surface of the water, but beneath it.
Here's one drying itself on a turtle.
This is one of the numerous species of tern. They are common birds of the seashore and rivers world-wide. The characteristic forked tail and the black cap on the head is what gives it away.
It is hard to say for sure given the chromatic aberration altering the colours, but this is likely to be either from the genus Sterna (particularly the Arctic tern or the ...
