    Mr. Shigenobu Tachibana donated his private bird collection to the Yamashina Institute for Ornithology. The donated collection totalled 276 specimens, consisting of 255 skins, two fluid-preserved birds, three feather sets and 16 eggs. Many of the specimens were collected from the Sanriku coast, northeast of Miyagi Prefecture, from 1949 to 2008. This area was damaged by the 2011 Great East Japan Earthquake and many museum specimens were lost. Therefore, these donated specimens from the Sanriku coast which were not destroyed by the earthquake are especially valuable for ornithology in Japan.

    In 2017 we continued the Monitoring Avian Productivity and Survivorship (MAPS) program in Fukushima, Japan, using constant-effort mist netting and banding. Preliminary results from six years of data, including adult abundance index, productivity index, and apparent adult survival rate, were analyzed. Adult abundance of the Japanese Bush Warbler Cettia diphone in Fukushima City gradually increased from 2013 to 2017, while that in Minami-Soma City was relatively stable. In Iitate Village, adult abundance of this species fluctuated greatly, with a low in 2016. Adult abundance of the Oriental Reed Warbler Acrocephalus orientalis in Minami-Soma City was higher in 2015–2017 compared to 2012–2014, while that in Fukushima City was low in 2015 and 2016. Adult survival of the Oriental Reed Warbler from 2012–2013 to 2015–2016 in Minami-Soma City was 0.23–0.34 (Ave=0.27), while that in Fukushima City was 0.12–0.22 (Ave=0.16).

    The Ministry of Agriculture, Forestry and Fisheries reclaimed Isahaya Bay to promote agriculture and prevent natural disaster, such as a storm surge. As part of surveys being conducted to monitor the environmental impact of this reclamation project we recorded bird species observed in Isahaya Bay and counted the number of individuals belonging to some orders, such as waterfowl and shorebirds. We divided the whole study period into three, based on the establishment of a sea levee and the completion of the project, and then compiled the change of avifauna corresponding to those periods. Before the reclamation project, Isahaya Bay was a major habitat for the birds living in tidal flats that represented the shorebirds. The establishment of the sea levee resulted in disappearance of the tidal flat; consequently, Pluvialis squatarola, Numenius qrauata, N. madagascariensis, Calidris alpina, Tadorna tadorna, Larus saundersi decreased in number. The project also established a regulating reservoir; thereafter, Anas strepera, A. falcata, A. penelope, Aythya marila, A. ferina, A. fuligula, Podiceps cristatus, Fulica atra increased in number. It is noteworthy that since 1997 when reclaimed land was created, the following endangered birds were regularly observed: the genera Anser (including A. fabalis and A. albifrons) and Grus (including Grus vipio and G. monacha), Circus spilonotus, Glareola maldivarum, Sterna albifrons and Falco peregrinus. As a shrub community including Mallotus japonicus, Ulmus davidiana and Celtis sinensis grew in the Phragmites australis community, the following species that inhabit the forest landscape increased in number; Aegithalos caudatus, Troglodytes troglodytes, Poecile varius, Eophona personata.
