The phrase bird-brain may be used to describe someone being silly, but this is not the case for ravens.
Long【C1】________for their intelligence, ravens are now known to be able to plan ahead, a skill previously thought to belong only to humans. Researchers learned ravens could remember key information for a future task through tests. Until now, some corvids—the family of birds that【C2】________ravens—have shown the【C3】________to plan beyond the present, for example by【C4】________food for later.
But the latest experiments revealed that ravens can【C5】________forego an immediate reward in order to get a better one in the future. In one of the tests, ravens were trained to use a tool to open a puzzle box in order to【C6】________a reward. And then, the ravens were presented with a tool to open a box and an immediate reward, but were only【C7】________to choose one or the other. Ravens remembered that the reward in the box was better than the immediate reward, and almost all of them chose the tool.
Ravens’【C8】________for planning is still unknown, but it may be similar to ours. The human brain stores memories of past events to guide decision-making about【C9】________and future events. Planning tends to come about when the higher【C10】________of a future reward is palpable, or when one imagines the happiness that will come by retrieving food in the future.
【C1】
