News Finding: In fact, they even had to leave their improvised laboratory in Peru for two days because it was overrun by army ants.
Paper Finding: Smaller species and those with higher wing loading may use arcing turns more often for a tactical or safety advantage.
News Context: The data gathering wasn't quite as easy as simply capturing the birds because of the conditions the researchers were in. In fact, they even had to leave their improvised laboratory in Peru for two days because it was overrun by army ants. Still, they were able to gather the data that shed light into the hummingbirds' impressive flight skill and agility.
Paper Context: This could be due to biomechanical differences that influence the efficiency of Arc and PRT maneuvers (such as wingbeat frequency, inertia, and/or mass distribution). Smaller species and those with higher wing loading may use arcing turns more often for a tactical or safety advantage. Our results show that performance and frequency of use are often related and that skill predominates.
