Description
<p>A line census was carried out to record the bird species that appeared at the Uchigo area of Mizusawa, Midori Ward, Sagami City, Kanagawa Prefecture from June 2010 to July 2018 (195 times, 8 years). We compared the number of birds, number of species and breeding status with data from 1999 to 2010. The following are the results.</p><p>1 From July 2010 to June 2018, 77 bird species were confirmed. From 1999 to 2018 there were a total of 111 species. A total of 107 species when the 3 introduced species and Rock Dove were exlcuded.</p><p>2 The seasons with the most bird observations were April and May when migratory birds arrived (60) species and November -January the following year when duck species increased (55 species). From summer to the beginning of Autumn there were 40 species.</p><p>3 The highest number of birds observed was from September to December and February the following year with an average of 450-850 birds observed at each survey. The next highest was in June with 350 species. These results show an improvement from the results from 1999-2000 which may be due to the increase in Mandarin Duck, Asian House Martin and Japanese Grosbeak.</p><p>4. There were 50 birds in the survey area that were confirmed breeding or thought to have bred ( excluding Chinese Hwamei and Rock Dove). Past survey was 52 species which just about matches this survey.</p><p>5. There have been 2 new birds added since 1999: Blue Rock Thrush, Chestnut-cheeked Starling. The summer and autumn migratory periods showed a decrease in birds and the Japanese Sparrowhawk was not observed. On the other hand Japanese Night Heron, Ural Owl and Crested Kingfisher were observed.</p><p>6 First records of Great Corrmorant and Blue Rock Thrush breeding by the waterside in this survey area.</p><p>7 The survey area is where the Sagami River and the Doshi Rivers join and is surrounded by Mt Takao and the Tanzawa Mountains. A unique arrangement. We will continue to study the birds of this area and record their movements along with collecting data from the Sagamihara greenbelt.</p>
