 In the first study to demonstrate different learning techniques in a single species , the noisy miner was found to employ different cognitive strategies depending upon the resource it was foraging . When searching for nectar , which does not move but is readily depleted , the noisy miner uses a spatial memory @-@ based strategy , identifying characteristics of the environment — a strategy that is efficient in new environments and is not affected by changes in the bird 's activities . When searching for invertebrates , it appears to employ a different strategy based on learned rules of insect movement ( they improve at finding invertebrates with practice ) . The two different strategies imply the existence of adapted cognitive mechanisms , capable of responding appropriately to different foraging contexts .
