troutsalmoncatfish Robins, parrots, and owls all have feathers and wings, so they are birds. Trout, salmon, and catfish live in water and breathe with gills, so they are fish.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Birds have wings that help them fly through the air.
Wings flap up and down to push air, which lifts a bird off the ground and keeps it in the sky.
2. Fish breathe underwater using their gills.
Gills are special body parts on the sides of a fish that pull oxygen out of the water so the fish can breathe.
3. A robin builds a nest out of twigs and grass.
A nest is a cozy bowl-shaped home that birds build in trees so they have a safe place to lay their eggs.
4. Most fish are covered in slippery scales.
Scales are small overlapping pieces like tiny shields that protect a fish's body and help it glide through water.
5. An owl hunts at night using its sharp eyes.
An owl has large, sharp eyes that can see in very low light, which helps it spot mice and other prey in the dark.
Part C: True or False?
Read each statement. Circle True or False.
1. All birds have feathers on their bodies.
True False
Feathers are one of the special features that make birds different from every other animal group — only birds have them.
2. Fish can breathe air just like people.
True False
Fish breathe with gills that only work underwater, while people breathe air with lungs — the two are very different.
3. Parrots are colorful birds that can copy sounds.
True False
Parrots have bright red, green, and yellow feathers, and they are famous for copying words and sounds they hear.
4. Salmon live in nests on top of trees.
True False
Salmon are fish, so they live in rivers and the ocean. Only birds build nests up in trees.
