April is the prime month of spring with trees and flowers showing lively fresh green colors. Cherry blossoms in full bloom are a highlight of the season but in April the number of plants flowering is not necessarily that many. Visitors may be able to observe more flower and blossoms in May.

The birds are also in their early period of transition from winter to summer. There is still a variety of ducks in the ponds. But they will be leaving to return to the north, so the numbers will decrease towards the end of the month. Some migratory shorebirds, such as Greenshanks and Whimbrels may appear on tidal flats in the park. Some lucky visitors may be able to observe the cherished song birds in the park towards the end of the month. Those are the Blue-and-White Flycatcher, Narcissus Flycatcher and Crowned Willow Warbler. They may stay in the park for only a few days on their way to mountainous areas where they will prepare for their breeding season.
  

One of the biggest tasks of the year for the rangers, is reed bed clearing work which was successfully carried out in the last month. We expect healthy and well-grown reed beds in the pond and hope active breeding of the Great Reed Warbler, Common Moorhen and Little Grebes in the summer.

 
 

April is the threshold of new cycle of nature from winter to spring. The month is also the threshold of new Financial Year of Japan. New students start the new school year and new employees enter companies with great dreams and visions. Many organizations make changes in the staff, including the Wild Bird Society of Japan as well. Ms. Shimamura and Mr. Aoki, after a few years of dedicated service in the park, will transfer to the Head Office of the society in Gotanda. The park receives new rangers Ms. Naganawa and Mr. Onda who are welcomed by the staff. We sincerely thank Ms. Shimamura and Mr. Aoki for their excellent performance in their period at the park.
