Greater Yellowlegs

On 22 March 2021, Erika and I watched as a Greater Yellowlegs gave a prolonged chase of another yellowlegs. This encounter was probably not sexual. In the field, you can not really tell males from females. Yellowlegs of all ages are known to drive off competitors from good fishing pools (Elphick and Tibbitts 2020)—apparently, that is what is happening here. These chases are usually infrequent and short, but can be longer in duration and can even result in pecking and kicking—although we did not see any physical contact.
