    Birds make their own body heat.

  2. Isaiah Daws says:

    Birds are endothermic and when they aren’t mating their reproductive organs shrink

  3. Riley Glause says:

    Birds’ wings are aerodynamic and they have strong chest muscles to help them fly.

  4. Megan Heineman says:

  5. Heather Pohlmeier says:

    Birds can generate their own body heat making them endotherms

  6. Salina says:

    Birds generate/make thier own body heat

  7. Raigan says:

    Birds have strong chest muscels

  8. Beatriz Rodriguez says:

    Birds have really strong chest muscles that help them fly.

  9. Tyler Steinacher says:

    They have a four chamber heart like humans.

  10. Isabel Contreras says:

    Birds create their own body heat. This means they’re endotherms.

  11. Jon R. says:

    Bird are a reptile like animal that have wings and a four chambered heart

  12. Lauren Rookstool says:

    They help the ecosystem by pollinating plants

  13. Austin Fransisco says:

    Aerodynamic wings and strong chests muscles help birds fly.

  14. Taylor Kool says:

    Birds are endothermic, which means that they generate their own body heat.

  15. Jordyn Retzlaff says:

    Birds are endothermic, so they can create their own body heat.

  16. Stetson Guyette says:

    Birds are endothermic and can fly using their aerodynamic wings

  17. Colton Helgoth says:

    Birds help the ecosystem by pollinating, dispersing seeds, and eating insects.

  18. Jacob Evans says:

    Birds generate there own body heat

  19. Sarah Hoban says:

    Birds can generate their own body heat, which is called endotherms.

  20. Birds help pollinate, spread seeds, and eat insects.

  21. Emily K. says:

    Birds have a four chamber heart, and very strong chest muscles to go with there aerodynamic body. (They also have light bones that help them become more aerodynamic)

  22. Taylor Wieland says:

    Birds can fly with the help of their aerodynamic wings and strong chest muscles.

  23. Darian Candle says:

    Birds generate their own body heat and can keep it constant.

  24. Sarah Ruzicka says:

    When birds aren’t mating there reproductive organs shrink

  25. Brandon Gannon says:

    There are many types of birds, there are aquatic, raptors, colorful, cavity nesting, perching, wading, and flightless birds.

  26. Ryan Wiese says:

    Birds can help the environment by pollinating plants, dispersing seeds, and eating insects

  27. Cody Schott says:

    Air first enters air sacs, and then it moves into birds’ lungs.

  28. Nicole Phinney says:

    Birds help the ecosystem by pollinating, dispersing seeds, and eating insects.

  29. Kyra Baker says:

    Birds that migrate long distances use the stars, landmarks, and/or the Earth’s magnetic field to find their way.

  30. Garrett Byerly says:

    Birds are a reptile like animal with wings that has a four chambered heart

  31. Keoni Kelly says:

    Birds are very similar to reptiles, with the main differences being that they are endothermic and they have higher metabolisms.

  32. Wyatt says:

    When birds are not mating, their reproductive organs shrink.

  33. Maddie Schultz says:

    Birds generate their own body heat and are called endotherms

  34. Alexis Pedersen says:

    Birds fly with the help of their aerodynamic wings

  35. ryleigh brandt says:

    birds down feathers keep them warm

  36. Shelby M. says:

    Birds are a lot like reptiles and thought to have evolved from dinosaurs.

  37. Abby Dvorak says:

    Birds have strong chest muscles.

  38. Mikayla H. says:

    Birds are like reptiles, but they can keep a constant body temperature.

  39. Hannah Eberl says:

    Birds down feathers keep them warm and make them aerodynamic. Aerodynamic means they generate there own body heat

  40. Alli Mehring says:

    Birds are like reptiles except they are endothermic and have a high metabolism.

  41. Devin Tatro says:

    Birds can fly with the help of their aerodynamic wings and strong chest muscles.

  42. Hayley Ehlers says:

    Birds can fly with the help of their aerodynamic wings and strong chest muscles.

  43. Sarah Rathman says:

    Endotherms are birds that can generate their own body heat.

  44. Bailey Parr says:

    Birds down feathers keep them warm and contour feathers make them aerodynamic.

  45. Kayla Bachle says:

    Birds can generate their own body heat which are called endotherms.

  46. Allie Carlini says:

    Birds evolved from the Jurassic creature Archaeopteryx.
