"That doesn't seem to be very fair on the geese flying at the front," said Lizzie sadly.
"Oh, it's quite alright," replied Bubbles, quickly cheering her up, "they take it in turns to be the one in front!"
"That's alright then," said Lizzie, pleased that the geese were sharing the hard work.
"What other bird groups do you know?" Edward asked, intrigued now.
"Some birds have lots of different group names depending what part of the country you live in," Bubbles explained, "but some that I know are - a charm of goldfinches, a wisdom of owls, a quilt of eider ducks, a quarrel of sparrows and a mischief of magpies."
"I can see why the goldfinches are called a charm," said Richard. "They are very charming little birds."
