I have had a pair of Yellow-legs here for a long time. Don't know if they are a pair I have studied in detail before or not. Kept in small outside cage.

A couple of months ago, I separated them. Leaving ♂ in old cage. Putting ♀ in new cage, about 15 ft from ♂. Going to put them together again this morning.

Putting her in 6:15 a m 

♂ immediately utters R. Declining into 2 or 3 soft Bzz's. With St?. Then flies away, perches some feet from ♀.

Difficult to see, as it is still somewhat dark here.

♀ just sits in corner. ♂ flits about, some distance from ♀. Does brief silent St. occasionally on landing. 6:17. Sometimes facing in direction of ♀. Sometimes facing away. ♀ flies to branch near ♂. ♂ responds by rocketing around cage, in very fast and unusually noisy whirring flight, uttering R's as he does so. ♀ flies away. ♂ relaxes
Falls silent 6:20.

♀ goes down to feed. Utters 2 or 3 single CN's as she does so

Both birds sitting quietly now, Not together.

♂ down to feed. Then ♀ goes down. ♂ immediately flies up. Apparently frightened of ♀. ♀ feeds. ♂ flies about excitedly near top of cage. Then ♀ finishes feeding, starts to fly up. Both birds silent except for occasional CN's until now. As the ♀ flies up, the ♂ swoops or pounces on her!! Brief chase. No vocalizations. Wings whirrs very noisy Chase ends with the two birds hanging on wires side cage. Can't see the
