A scrub jay

 

can remember when it cached a particular piece of food in a particular place, researchers have discovered, and tend not to bother to recover a perishable treat if stored long enough to have rotted.

 

a错在主谓不一致。

researchers have discovered,是插入语，在分析句子结构时可以不用管它。所以句子的主语实际只有一个就是“A scrub jay”，and后面的并列句的动词当然也就要用第三人称单数了。
