Abstract
From the results of these three papers published in the special feature, "Study of breeding ecology of birds using temperature sensors", we have concluded that using temperature sensors is an effective method for researching the breeding ecology of birds. Video recording of nests gives us more detailed data for studying the breeding ecology than does the temperature sensor, however, it take long hours to review and analyze the video data. We can analyze temperature sensor data easily because we can download the data to computer. Furthermore, the sensor is inexpensive (less than 3000 Japanese Yen), and the sensor and data logger is reusable. Therefore, we recommend the use of temperature sensors for studying the breeding ecology of birds.
