What metric do biologists track upon the AWBP's arrival in Texas to gauge the success of the northern breeding season?

Answer

The ratio of juveniles to adults in the migratory flock

Monitoring the health and recruitment rate of the Aransas-Wood Buffalo Population is vital for assessing conservation outcomes. A crucial way biologists gauge the success of the breeding season that just concluded up north in Wood Buffalo National Park is by closely observing the composition of the flock upon its arrival at the Texas coast between November and March. Specifically, they track the ratio of juvenile birds (young birds) compared to the established adult population. A high influx of young birds signals that the remote northern grounds successfully produced enough new recruits to offset losses incurred during the long migration or the previous winter stay, thus ensuring population viability.
