Sammy was a cute sparrow.
He flew over the river with his mom.
"Oh, Mom, it's cloudy today," Sammy said.
"Yes, Sammy," said Mom.
"It looks like it will rain soon."
"Mom, I'm hungry," Sammy complained.
"Yes, I'm also hungry.
Let's find something to eat."
"Mom, Mom!" Sammy said.
"Rest in the woods.
I will go and get some food."
"Can you do it by yourself?" Mom asked.
"Sure, I can!" Sammy was old enough to find food on his own.
He was a good flier too.
He flew around the river to look for insects.
But he couldn't find a single one.
"Hmm, this is strange.
Why can't I find any insects?" he wondered.
Sammy felt tired and went back to his mom.
"Mom, I searched hard, but I couldn't find a single insect.
I used to see insects everywhere, but now they are gone."
"Sammy, why don't you fly low?" Mom suggested.
"What? You want me to fly low?" Sammy asked.
"Yes, fly low.
Then you will see the insects."
Sammy took his mom's advice.
He flew around the river again.
This time he flew low.
"Wow! I couldn't find a single one when I flew high," he said.
"Now I can see many insects. Yay!"
Sammy caught a big insect and brought it to his mom.
"Mom, I don't understand.
Why are all the insects so close to the ground?"
His mother explained.
"Before it rains, the air gets moist.
The moisture in the air makes insects' wings heavy.
So the insects fly in the grass and bushes near the ground."
Sammy understood. "I get it!
So when it looks like it will rain, I should fly low to look for insects."
"Right!" said Mom.
Just then it started to rain.
Sammy and his mom watched the raindrops and smiled.
