Abstract:

Since the 1950s Lesser White-fronted Geese Anser erythropus decreased dramatically all over the wide-spread breeding area (Mikander 2015). Nowadays Lesser Whitefronts are one of the most endangered waterbird species in Europe (BirdLife International 2015). Krüger & Kruckenberg (2011) could show that the species has been frequently observed in Lower Saxony since the beginning of the 20th century. From 2012-2015 a research project of NABU Lower Saxony intensively investigated the importance of Northwest Germany for this species. As a result we present new and supplemented data on the occurrence of Lesser White-fronts in Lower-Saxony for the period 1980–2016. In this period, a strong increase in the number of observations occurred, such that Lesser White-fronted Goose has stated as a regular, annually occurring migratory bird in Lower Saxony. The number of observations in Lower Saxony peaked in the years of 1999/2000 to 2007/08 and decreased thereafter. A clear pattern in spatial distribution can be identified in the northwest of Lower Saxony in the region of East Frisia. This includes the Dollard-Lower Ems-Region (Rheiderland, Emsmarschen) with the Krummhörn, including Leybucht, which are key sites for the species. Other important sites are the Middle Elbe and the Lower Elbe. Unfortunately, information about the origin of the birds is rare. More than half of the Swedish Lesser Whitefronts are colour-marked, but the occurrence of many unmarked birds presumably consists of a mixture of Russian and Norwegian birds. Taken together all data show Lower Saxony (Northwest Germany) as a part of the range of Lesser White-fronted Geese migrate to The Netherlands and probably also for wintering individuals. So, this should be incorporate in legislative protection (f.e. key species in Bird sanctuaries or hunting regulation).

Abstract:

The critically endangered Fennoscandian Lesser White-fronted Goose Anser erythropus population is currently estimated to number roughly 100 individuals. Following a dramatic long-term decline to only some 10 breeding pairs in 2007–2008, the population has since slowly been increasing. The spring staging of the population on the Finnish Bothnian Bay coast has been monitored by the WWF Finland Lesser White-fronted Goose conservation project since 1985. In spring 2017, 124 individuals were counted, which was the highest number during the history of the monitoring. The Bothnian Bay coast was historically also an important autumn staging area and since 2020, the geese have again been staging in the area also during autumn migration. Breeding of the species has not been recorded in Finland since 1995, but the likelihood of locating breeding pairs again in Finnish Lapland is considered to be increasing, as the Norwegian breeding population is growing. As a part of the current international Lesser White-fronted Goose EU LIFE project (wwf.fi/lwfg), environmental DNA is being used to map potential breeding sites in Finland.

Abstract:

In the period from 1907/08 to 2006/07, i.e. 100 winters, 156 records of 261 Lesser White-fronted Geese Anser erythropus were reported in Lower Saxony. The first records were from 9 December 1907. For the period before 1970, only accidental occurrences were reported. A large increase in the number of records occurred in the 1990s and continued in the 2000s. Since the mid-1990s, the Lesser White-fronted Goosehas become a regular, annually occurring migratory bird in Lower Saxony. There is evidence of a concentration of records in the north-west of Lower Saxony in the region of East Frisia, especially in the Dollart-Lower Ems-Region (Rheiderland, Emsmarschen) and the Krummhörn including Leybucht, which are key sites of the occurrence. Other important sites are the Middle Elbe and the Lower Elbe. During autumn migration, the first Lesser White-fronted Geese reach Lower Saxony in mid-October. From early December the numbers rise steadily until early March and peak in the first decade of March (median = 2 March). After that the numbers decrease but birds remain until the first third of April at a relatively high level, and birds are gone by the end of April. In 139 cases (92.1%), Lesser White-fronted Geese were recorded only on a single day, longer stays were reported only twelve times (7.9%, n = 151 records), the longest 27 days, indicating overwintering. About 93% of all observations of Lesser White-fronted Geese refer to birds which were associated in only small flocks of three individuals, and often only single birds (68.6%) occurred (n = 156 flocks and 261 ind.). “Large” flocks have been recorded rarely. 141 Lesser White-fronted Geese were reported as adult birds (86.5%), with only 21 individuals identified as juveniles (13.5%, n = 163). In 75% of records since the mid-1990s (73%, n = 70 records) Lesser White-fronted Geese were roosting with White-fronted Geese A. albifrons. In 19% of the records they were with Barnacle Geese Branta bernicla, and in 9 % with Greylag Geese A. anser. There is a high likelihood of confusion between Lesser White-fronted Geese and Whitefronted Geese during goose hunting, which is usually practiced at dusk at the night roosts of both species. Therefore, to collect data for better protection of Lesser Whitefronted Geese in Lower Saxony we started a new research programme in autumn 2012 involving field research, satellite tracking and colour-marking as well as an awareness campaign for birders, hunters and the general public.

Abstract:

Lesser White-fronted Goose Anser erythropus is recognized as a globally threatened species. Very small numbers stage and winter in Japan, mostly individually, as families or sometimes in small flocks. Since beginning to observe this species in 2001 at Sarobetsu, northern Hokkaido, Japan, we have noted increasing numbers. The increase, from a few individuals (2001–2004) to flocks (2005–2007), is of interest, given the threatened status of this species. Lesser White-fronted Goose now regularly migrates through Sarobetsu, giving us opportunities to observe this relatively rare winter visitor to Japan. In order to help clarify the status of this threatened species in Japan, we describe and discuss the change in numbers, the proportion of juveniles in flocks, family size and length of stay.
