do birds have urinary tracs like humans?

Birds expell solid & fluid waste at the same time.  They have a different system to us.

No, all animals do not breathe like us.\n\nBirds for example have an very different arrangement to their lungs. You and I have to take a breath in to absorb air and then take a  breathe in and then breathe out to expel it. A bird takes a breath in and a breath out at the same time. Every breath for a bird absorbs air and expels used air at the same time. That makes birds far more efficient at breathing than a human and also makes them far better at singing since they can make sound even while breathing in if they wish.\n\nMost land animals don't even have lungs and don't need to draw air into their bodies. Instead they absorb air directly  through their skin.\n\nEven something as similar to us as a frog can breathe mostly thorough its skin. All frogs have lungs that they can use to breathe but the lungs are used mainly for when the whether is dry. Many species of frogs have very small lungs, and the lungs can be surgically removed without having any effects at all on the frog. So long as the skin is kept wet a frog is perfectly capable of breathing through its skin.\n\nAnimals like slugs, snails and worms also breathe through their skin.\n\nIn the case of worms they have no other organs to breathe with. They are entirely dependent on their skin to breathe and the skin has to be kept wet or they suffocate.\n\nSnails breathe not just through their skin but also through a set of gills tucked up under the shell. It might seem strange that a land animal would use gills to breathe, but snails evolved from sea animals and have retained the same method of breathing.\n\nSpiders also use what is really a modified gill in order to breathe. The gill consists of a set of plates, like the pages in a book, hanging inside a pouch on the back segment of their body.\n\nInsects can't breathe very much through their skins, but they don't breathe through their mouths like we do. They instead have a series of holes along their sides that they use to breathe through. Those holes are connected to a series of pipes that run right through the animal. Imagine a person with holes in their side the size of the cardboard roles from toilet paper. You could see right into the holes all the way to the heart or guts, and those holes are the way that air gets into the body. Insects use pretty much that method. It's pretty , weird but it works for them.\n\nThere are many other ways that land animals breathe, but those are the main ones. Either they breathe through their skins like frogs or worms do, the have modified gills like snails or spiders or they have tubes running through their bodies as insects do.

The chalky-white paste called urate (made of uric-acid crystals) is a byproduct of bird kidneys. What you actually see is the color of the whitish crystals. Swimming in urate is a chunk of stool (solid waste). This piece is usually hard and worm-like, and gets its color from the bird's diet. Hues range from greenish for birds who feed on plant seeds and green vegetables, to brownish for brown birdseed, and reddish for strawberries. For shrimp-eating seabirds, it's pink!\nTo top it all off, bird poop contains a tiny sprinkle of urine. Why so little? "Aside from the ostrich, birds don't have bladders and can't carry a lot of water around. They'd be too heavy to fly," explains ornithologist (bird expert) Jerome Jackson at Florida Gulf Coast University. (By the way, the ostrich can't fly.)\n\nThink bird poop is just waste? Think again. Veterinarians see it as an indicator of bird health. Abnormal colors like red urine and urate may be signs of internal bleeding. Brown urate may signal lead poisoning, and green or yellow urate may mean liver disease. Colorful indeed!

frogs have a cloaca, a single reservoir for both urine and feces.  Fortunately in humans these are divided so we have one opening for urine and another for feces.

Good question.  \n\nBird metabolism is super fast.  So they eat enough to support themselves, and it turns to birdy fat.  Then they eat some more and it partially digest, They cough that up and feed their chicks with it.

Kangaroos have a way of internally recycling their urine to conserve water, the urine they pass can be very concentrated. \nThere are a couple of types of frogs that survive underground for several years during drought. When it does rain, they come out, have babies, then have a very big drink, bloat up, go back into hibernation until the next wet season. They're called, aptly, the Water Holding Frog\nHere's a link:\nhttp://frogsaustralia.net.au/frogs/display.cfm?frog_id=127

Yes they are called birds.

"Bears don’t pee or poop when they hibernate. Their bodies recycle or simply stop making what normally needs peeing out every day"

ok\n Hoatzin chicks have archyopterix-style claws on their wings\n\nPuffin`s beaks are not as colourful out of the breeding season\n\nThe Goatsucker (no, not el Chuppacabra, the bird!) of the USA is called a Nightjar in the UK\n\nAmerican Robins are not related to european Robins, they are in fact a type of thrush\n\ncormorants have to open their wings to "dry" them as they`re not as waterproof as other waterbirds.

One word answers are not possible. If your teacher wants single word answers she is a moron.\n\nBirds, snakes and humans breathe using lungs.\n\nFrogs breathe using their skin and their gills when they are young and using their skin and lungs as adults.\n\nFish breathe using their skin and gills and also commonly use their swim bladder, mouth and stomach to breathe with.\n\nThe same applies to movement. Humans can move by walking or climbing or swimming or riding or driving or a bazillion other methods.\n\nFrogs and snakes may swim, or walk or hop or burrow or climb depending on the species and where it is.\n\nBirds may swim or fly or walk or hop or burrow or climb depending on the species and where it is.\n\nThere simply are no single word answers to these questions.

I can show you a website that's a little technical, but should help.\n\nThe basic answer is, not really.  Most lizards are designed not to waste water, so they don't "pee" in the same sense a dog or a cat does.

because instead  being the solids that birds cannot digest (like humans) bird poop is made of concentrated uric acid which appears white.

Because they are fowl

Mamals (teradactyles) used to fly with leatherlike wings so it would seem that humans could also.  However human arm and chest muscles are not very suitable for flight.  As in the term pigeon or chicken breasted, birds have muscular chests that fascilitate a powerful downward pull on the wings.  Coonsider the shape of a turkey breast and the thick breastmeat there.  Still, the only way a turkey can soar with the eagles, is in their talons.  We would tire too easily, even with very light fake wings.

put the bird in a diaper before you go for a  ride

If you're talking human body, it's the Gluteus maximus.\nA bird... the breast/pectoralis muscle... but I'm assuming you meant humans.  ;)

i did a small unit in animal behaviour and physiology and from what i remember .. birds have a much narrower vision (acuity of vision) which enables them to detect preys for examples from large distances while flying .. thats all i know, it not ... mm .. that informative.. but i hope it helped .. lol
