Though I Used To Think That

The male birds never sings for the joys of the Spring
With them  song is a territorial thing
They sing to warn males of their kind from their patch to stay clear
And they only use song as a weapon of fear
And yet i recall when i was a schoolboy
I thought that birds sang only for love and joy
Till one far more knowledgeable on Nature than me
Informed me that birds only sing to defend territory
At nesting time any male of his own kind he does not treat as a friend
His song born of aggression with nesting borders to defend
We never stop learning as some like to say
And of Nature we learn something new every day
At nesting time birds never sing just for love and for joy
Though i used to think that when i was a young boy.
