The park was calm and still chilly today.  
In a desolate wintry scene, however, red blossoms were very conspicuous as if they talked about early spring. Those were Red Plum blossoms Prunus mume and Sasanqua Camellia Camellia sasanqua.  They are not only beautiful but also profitable for some bird species.  For Japanese White-eyes and Blown-eared Bulbuls the nectars of these flowers are their favourites.

A noteworthy feeding behavior was seen in the west side of the park, at the garden space.
The photos below are the feeding shots of a Japanese Tit and a Japanese Pygmy Woodpecker.  Both of them fed eggs in oothecae of Giant Asian Mantis Hierodula patellifera.

Eggs in oothcae of mantises have high nutritive value for insectivorous wintering birds in the park.

Grass bushes and shrubs in the west side of the park, where mantises lay eggs, were however reduced dramatically in the garden area because of over management and bush clearances. This may cause to increase feeding pressure on eggs and cause to decrease population sizes of the mantis species in the area.

The following is the list of species that park rangers observed today.

Mallard、Northern Pintail、Common Pochard、Tufted Duck、Little Grebe、Great Cormorant、Grey Heron、Eurasian Coot、Snipe、Common Sandpiper、Black  Kite、Eurasian Sparrowhawk、Northern Goshawk、Common Buzzard、Oriental Turtle Dove、Common Kingfisher、Japanese Pygmy Woodpecker、Bull-headed Shrike、Large-billed Crow、Japanese Tit、Brown-eared Bulbul、Japanese Bush Warbler、Japanese White-eye、White-cheeked Starling、Pale Thrush、Brown-headed Thrush、Dusky Thrush、Daurian Redstart、Eurasian Tree Sparrow、White Wagtail、Oriental Greenfinch、Hawfinch、Black-faced Bunting、Reed Bunting (34species)

The park is continuously under severe cold.  Nearly all streams and ponds in the park except “Shio-iri” Pond were frozen over.  They kept off waterfowls thus the park was slightly deserted today.

At East Freshwater Pond in the morning a Great Cormorant attempted to alight on the water. Just before landing the bird realized that the thick ice formed on the water. It turned immediately to climb steeply and flew away.

(“Go around!”)

In another occasion a male Pochard was seen in the pond alone.  There were pieces of ice around the bird.  He could has been tried assault landing.

In the afternoon as the northwest seasonal wind began to blow, a considering number of Grey Herons concentrated on the east bank of “Shio-iri” Pond for avoiding the wind.

In the west side of the park at the vegetable garden a Rustic Banting was observed. The species is uncommon winter visitor in the park.

The photo below is a view of East Freshwater Pond from East Observation Blind.  The pond was frozen over in the morning.

On bare grounds and foot passes frozen columns also formed in places.

At this time of year visitors may encounter mixed-species flocks of different insectivorous species.  These flocks are particularly common in winter season. Japanese Tits and White-eyes are nuclear species in the park.  A Japanese Pygmy
Woodpecker often joins to flocks as a minority species.

In some case, however, if you were lucky you would be able to see three woodpeckers in a flock.

“Scenes in the middle of winter and remarkable birds today”

The park is under unusual severe cold these days. Nearly all ponds and streams froze in the morning.

Below photos show thin ices formed on the water in West Freshwater Pond and the stream in the western side of the park.

On the other hand at warm sunny spots, such as Lawn Square, flowering Shepherd’s Purses Capsella bursa-pastoris were seen as a herald of spring.  The plant is famous in Japan as one of the seven plants consumed in Japanese Spring-time Festival.

In the reed bed near Nature Centre, Japanese White-eyes and Reed Buntings actively moved around and fed insects hidden in the sheaths.
