Juvenile calling near probable natal territory.
观察细节
Heard juvenile calling (at a distance) as soon as I arrived in the area. Possibly it heard me, but likely did not know I was present until I moved closer and made the recording. Calling from same patch first observed 07/01/25 (call today sounds very similar to recording made that morning). At times moving towards Irwin Run and natal territory, although much of time calling fairly close to me. Left area after making recording. As far as I could tell, there was no response from the adults.
