Oh wow, not Carl Werner's garbage.
1. More time passed between Archaeopteryx and T-Rex (90 million years) than passed between T-Rex and humans (65 million years).
2. Birds were already evolving in the Jurassic so it's not surprising they would be found in Cretaceous strata.
3. Boa constrictors are snakes, not birds.
4. The fossils of every type of bird you mentioned has the word 'like' after it. "Owl-like", etc.
5. Your own uncited source notes that the find wasn't a modern duck or goose, but a relative.
These things you're pointing out is kinda stupid though. I mean, according to the geological record, a vast diversity of birds, modern day birds have been found to be walking with dinosaurs up to 200 million years ago. And it isn't just birds, but also salamanders, lizards, flying squirrels, platypus, rabbits, beavers, crayfish, lobster, mayflies and many others. Fossils of modern trees have also been found with the dinosaurs, including sequoias, redwoods, sassafras, walnut and palm. If it looks like a duck, quacks like a duck, it's a duck.
Here's an Avocet in the dinosaur exhibit at Milwaukee Museum - a rare example of a modern bird in such displays. A living fossil.
If you see the fossil record we should see examples of about 90% dinosaur 10% bird creatures, 80% dinosaur and 20% bird creatures, and then 70% dinosaur and 30% bird creatures... and so on, (and remember, slow and gradual that's how the theory of evolution works.) When we get somewhere in the middle evolutionists like to point to something like an Archaeopteryx which evolutionists believe is one of these transitional forms, then all of a sudden we get a vast diversity of birds.
Now what we actually notice in the fossil record where there should be millions of these "transitional" forms yet we hardly find any. They are called missing links for a reason... they're missing. I think it strange that an evolutionist would try to fool people to actually believe that a dinosaur evolved to a chicken with no evidence whatsoever, yet penguins remained penguins 100 million odd years later? The more we know the less and less the evolutionary theory makes any sense. I really don't know how an evolutionists brain comprehends and willingly accepts this nonsense.
I'll provide you with sources outside of the creation spectrum to denote any apprehension of bias, but simply an acknowledgment of a universal fact regardless of where you stand. There are plenty out there.
