I love hearing that - and look what all the buzz was about! Janae Parkin saw a gigantic (3 foot by 4 foot) beehive in a yard that had just got a tree trimmed back on it's leaves - Surprise!
Early in the morning the bees huddle together and we can see the clear folds and ridges in the beehive.
This is early in the morning.
This is in the afternoon sun and as it warmed up the buzz got bigger and the swarm larger.
