How Birds Evade Predators: Survival Strategies and Behaviors

Uncover the fascinating survival strategies and behaviors that birds use to evade predators of their pure habitats.

1. Introduction

Birds rely on flight as their main strategy of escape from predators, making their flight abilities important for survival. Impaired flight on account of elevated wing loading may make birds additional weak to predation. To counteract this, birds have the facility to independently decrease physique mass (BM) or improve pectoral muscle mass (PMM) in response to elevated wing loading.

1.1 Nearshore vs. Farshore Foraging

The study focuses on evaluating nearshore and farshore foraging shorebird species to develop an idea on their predator escape methods. It hypothesizes that nearshore foragers should reply to elevated predation by rising their PMM to promote speed-based escape, whereas farshore foragers should decrease BM to boost agility for maneuvering escape.
