When chickadees are upset they are saying dee-dee-dee-dee-dee however their message is completely different relying on predator dimension. As reported in a 2005 examine of black-capped chickadee alarm calls:
The bigger a predator’s wingspan or physique size, the less “dee” sounds the chickadees used of their alarm name, the examine discovered. The other was true for smaller predators –– the songbirds would use extra “dee” sounds in the event that they encountered a smaller fowl, which may very well be larger threats to chickadees since they’re extra agile.

When chickadees see a red-tailed hawk they offer a warning however these hawks are massive, comparatively sluggish, and unlikely to seize a chickadee.
So the chickadees decelerate their warning dee’s … like this.
Alternatively, northern saw-whet owls are small and agile, simply the appropriate dimension to seize chickadees. You’ll be able to see how small they’re as I held one at an owl banding in 2016.
So when a chickadee sees a saw-whet owl …
… his warning name is frantic … like this.
By the best way, the chickadee warnings on this audio had been recorded at State Sport Land No 203 in Wexford, PA whereas the birds had been alarming at an Jap Screech-owl. Screech-owls are one other harmful predator of chickadees.
While you hear chickadees, pay attention for his or her warning calls to let you know how huge the predator is.
If I may discover some frantic chickadees, I’d discover an owl.
