It is a quite hot day (30 degrees Celsius) for this location. It usually hovers around 25 degrees. The jackdaw was walking about with another jackdaw looking for food, actually pecking some dead insects off of a cars bumper. The other jackdaw did not have its beak open.
Is this a cooling behavior, perhaps similar to when dogs pant?
It’s a good idea to leave a shallow dish if water in a shady spot for bitds on hot days, cause yes that’s one hot bird ;)
