These are the frustrating photographs. They should be easier, the little ones are going no where. However, the adult might.
So keep them in the view finder, keep focus and wait for the right moment. Also, remember to bring the monopod next time, the long gear is too heavy.
The little ones keep flopping over. First one, then the other, next both. All I wanted was the two upright at the same time.
After 50 images, and holding the camera up, and steady, I may have one. If not, so be it. This gear is heavy.
