<unk>  refers to the<unk>  behaviour<unk>  by<unk> s. Chemicals released into the natural environment by humans impact the behaviour of a wide variety of animals. The main culprits are endocrine-disrupting chemicals (EDCs), which mimic, block, or interfere with animal hormones. A new research field, integrative behavioural ecotoxicology, is emerging. However, chemical<unk> s are not the only anthropogenic offenders. Noise and light pollution also<unk><unk>  behaviour. This topic is of special concern for its conservation and human health implications and has been studied greatly by animal behaviourists, environmental toxicologists, and conservation scientists. Behaviours serve as potential indicators for ecological health. Behaviour can be more sensitive to EDCs than developmental and physiological traits, and it was the behaviour of eagles that first drew attention to the now well-known dangers of DDT. However, behaviour is generally difficult to measure and can be highly variable. Behaviours which are critical for survival, such as reproductive and social behaviours, and cognitive abilities like learning can be affected directly or indirectly by chemical<unk> s— many examples have been documented, and their chemical culprits have been identified. These same behaviours can also be altered by anthropogenic noise and light, although their mechanisms are relatively unknown.
