Could the blue jays ever have had thin beaks? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)
Grace [21]

Answer:

i believe the answer is 2)

Explanation:

because birds that eat seeds need to have thinner beaks in order to get to the seed. seeing as how their beaks are currently too large for that, they wouldn't be able to reach the seeds- they would have to adapt to the new environment **if that were to happen**

good luck :)

hopefully, this helps

**please let me know if this was incorrect**

have a nice day !!
