rewatch

Explanation:

The Grants' finch - tagging research focused on tracking aspects related to finch reproduction (mating frequency, offspring number) and physical traits (weight, beak size). However, tracking the number of seeds each finch ate daily is not feasible through tagging as it's difficult to directly observe or measure seed consumption at an individual finch level from tagging. Weight and beak size can be measured, mating frequency and offspring number can be monitored with tagging - assisted observation.

Answer:

the number of seeds they ate each day
