You can tell a lot if you hear them.
Where they're at.
What they're doing.
Are there females.
Do they know if you are there.
Absence of hearing them does not necessarily mean anything, but for sure hearing them means a great deal.
If I have time I wait to hear them before I start calling.
Plus that gives time for any news of my arrival to be forgotten.
