An integrated animal tracking technology combining a GPS tracking system with a UAV

Global Position System (GPS) tags are widely used in animal tracking to address far-ranging ecological, behavioural and conservation-related questions. However, GPS tags with transmitting functions via Global System for Mobile communications (GSM) and long-lasting batteries are too cumbersome for...

Marine litter pollution of breeding colony and habitat use patterns of Black-tailed gulls in South Korea

Marine litter can affect the survival of the breeding population in seabird colonies. In this study, five 5 m × 5 m quadrats were installed at a Black-tailed gull (Larus crassirostris) breeding colony on Nan Island to collect marine litter and regurgitated pellets, from which the types, sizes, an...

Continuous behavioural monitoring reveals increased feeding time during wing moult in free-ranging Pacific Black Ducks Anas superciliosa

Many waterfowl species go through a wing moult where all flight feathers are lost simultaneously, rendering the birds flightless while their feathers are regrowing. This puts constraints on the birds during this energetically and nutritiously demanding phase in their annual cycle.

Revealing increasingly detailed insights in animal behaviours using continuous on-board processing of accelerometer data

Studies of animal behaviour, ecology and physiology are continuously benefitting from progressing biologging techniques, including the collection of accelerometer data to infer animal behaviours and energy expenditure. In one of the most recent technological advances in this space, on-board proce...

GPS tracking of the two subspecies of the Eastern Buzzard (Buteo japonicus) reveals a migratory divide along the Sea of Japan

In the Far East, multiple avian lineages show a common divergence pattern between the Eurasian continent and the Japanese Archipelago across the Sea of Japan. Buteo japonicus burmanicus and Buteo japonicus japonicus are often regarded as a pair of subspecies of the Eastern Buzzard that differenti...

Sex-Specific Movement Responses of Reeves’s Pheasant to Human Disturbance Importance of Body Characteristics and Reproductive Behavior

Human disturbance has a strong impact on the movement of wild animals. The Reeves’s Pheasant is listed as an endangered species by the International Union for Conservation of Nature (IUCN) and a nationally protected species in China. This study evaluated how the movement patterns of this species...

Breeding movements of black-fronted ternstarapirohe (Chlidonias albostriatus) caught on the Waiau ToaClarence River during the 2021 breeding season

The scale at which protected area networks have been considered in Aotearoa New Zealand has evolved from focusing on relatively small, representative ecological areas to developing aspirational landscape-scale restoration over the last c.50 years.

Continuous on‐board behaviour classification using accelerometry – a case study with a new GPS‐3G‐Bluetooth system in Pacific Black Ducks

Over the past two decades, accelerometer (ACC) data have been increasingly used to study animal behaviours and energetics. However, the large amount of raw ACC data can be a burden to device storage and power consumption and in many cases may also require device retrieval for data collection.

[In Korean] Animal Home Range Estimators – A Review and a Case Study

Animals exhibit certain behaviors and movement patterns as they react to their internal needs, external stimuli, and surrounding environments. They have a bounded range in which they mostly spend their time, and it is referred to as a home range.
