在沙漠蚂蚁（Cataglyphis fortis）的栖息地，白天通常有持续不断的风。当访问熟悉的食物源时，蚂蚁会沿着喂食器顺风行驶一段距离，而不是尝试直接接近，特别是可能会错过小的食物源。在顺风区域，蚂蚁会吸收食物散发出的气味，并顺着它逆风寻找猎物。这种策略节省了大量的步行距离和时间。顺风策略所需的额外路径仅为约 0.75 至 2 m，具体取决于巢穴-喂食者的距离，而错过逆风侧的食物会导致更长的搜索轨迹。在最初的三到五次到达觅食地点时，顺风距离和接近路径长度显着缩短，并且接近轨迹变直。沙漠蚂蚁的行为进一步表现出相当大的短期灵活性。有经验的个体显然能够根据当前的风向（白天略有波动）来决定离开巢穴时选择哪个方向朝向喂食器。风向的显着变化主要发生在夜间。为了使巢穴与喂食器之间的距离更大，动物会在早上第一次觅食时根据风向的变化调整它们的路线。
In the habitat of desert ants,Cataglyphis fortis, a constant wind is usually blowing during the daytime. When visiting a familiar food source, the ants steer some distance downwind of the feeder, rather than attempting a direct approach that might miss small food sources, in particular. In the downwind area, the ants pick up the odor plume emanating from the food and follow it upwind to the prey. This strategy saves considerable walking distance and time. The additional path necessitated by the downwind strategy is only about 0.75 to 2 m, depending on nest–feeder distance, while missing the food on the upwind side results in much longer search trajectories. During the initial three to five visits to a feeding site, downwind distance and length of the approach path are shortened notably, and the approach trajectory is straightened. Desert ants further exhibit considerable short-term flexibility in their approach. Experienced individuals are evidently able to decide upon leaving the nest which direction to choose toward the feeder, depending on current wind direction (that fluctuates slightly during the day). Notable changes in wind direction occur primarily overnight. For larger nest–feeder distances, the animals adjust their approach en route to the altered wind direction during their first foraging trip in the morning.
