Know Your Eagles: Quiz 1
Question #1: What is an Eagle’s temporary ‘belly button’ called?
Yolk Sac Scar
Sorry! The answer was 'Yolk Sac Scar'!
Question #2: What is the pouch along the esophagus used for storing and moistening food?
Sorry! The correct answer is 'Crop'!
Question #3: Can Bald eagles swim?
Yes! They can 'flap' their wings to move through the water.
No! Their wings aren't able to function in water.
Sorry! The answer is yes! Bald eagles use their wings in a butterfly motion to 'flap' towards a dry spot: a muskrat or beaver den, shore, or even floating debris.
Question #4: Eagles have tiny projections on the underside of their toes that aid in catching prey. What are the projections called?
Sorry! The correct answer is 'Spicules'! Talons and a Hallux Claw aid in catching and holding prey, but they aren't spicules.
Question #5: How many components are there in bird droppings?
One: Feces (poop).
Two: Feces (poop) and indigestible prey remains.
Three: Feces (poop), urates (urine), and clear liquid.
Four: Glue, tarpaper, tape, and epoxy.
Sorry! The answer is feces, urates, and clear liquid! If you'd like to learn more about bird droppings, follow this link (it opens in a new window):
Question #6: True or False: Bald eagles cannot roll their eyes from side to side.
True: Their eyes are fixed within their skulls.
False: Their eyes are mobile within their skulls.
Sorry! The answer was true! An eagle's large eyes take up so much room in its skull that they don't have space for the small muscles that allow humans and many other animals to roll their eyes from side to side. Eagles turn their heads instead of rolling their eyes.
Question #7: In English, an Eagle sneeze is called a/an:
Sorry! An eagle sneeze is referred to as a 'Snite!' Achoo is the English onomatopoeia for a human sneeze, and Hapsu is Turkish for the same!
Question #8: Are bald eagles altricial or precocial birds?
Altricial! Eaglets hatch with their eyes closed and are not ready to leave the nest in two days.
Precocial! Eaglets hatch with their eyes open and are ready to leave the nest in two days.
Sorry! Bald eagles are altricial. According to Stanford University, altricial birds hatch with their eyes closed, are incapable of departing from the nest, and are fed by their parents. This fits the lifestyle of bald eagles, who spend roughly 75-80 days in the nest before fledging. You can learn more about the difference here:
Question #9: What are wing and tail feathers called?
Flaps and Rudders.
Wingers and Tailers.
Remiges and Retrices.
Primaries and Secondaries.
Sorry! Wingfeathers are remiges and tailfeathers are retrices. Flaps and rudders are found on airplanes, and primaries and secondaries are two types of feathers.

About 2.9 inches long and 2.2 inches wide.
About 6 inches long and 5 inches wide.
About 1.1 inches long and .8 inches wide.
About 1.5 inches long and 1.2 inches wide.
