Then, a drought happened in 1977, leaving the Medium Ground Finch population at 93.

Then in 1977 there was an average of 4 seeds per square meter. Then in 1978 -1979 the seeds and plant of the Portulaca plant died off while the larger harder seeds of the Tribulus plant thrived.

This made most of the birds die off, leaving the ones with larger beaks still alive.

The medium ground finch had a hard shelled beak, which helped them eat tribulus seeds, which let them live longer, while the birds who couldn’t eat tribulus seeds dies off.
