Moreover the bar-headed goose, the opposite species that died had been the shoveler, the river tern, the pochard and the frequent teal.

An 11-year-old boy died at All India Institute of Medical Sciences in Delhi final yr as a consequence of avian influenza, nation`s first fatality. India reported the primary outbreak of avian influenza in 2006.

RSPB Scotland is asking for an emergency native moratorium limiting capturing on the Solway for the remainder of the wildfowling season.

It requires pressing motion to cut back the devastating impacts of avian influenza. New statistics from the latest counts present that the UK is that this winter experiencing the worst outbreak of this lethal illness on document, with migratory geese which `over winter` on the Solway being the toughest hit.

Based on RSPB Scotland, the most recent inhabitants counts of the Svalbard barnacle goose present a drop in numbers from 43,703 in November final yr to 27,133 on this month`s rely. This represents a decline of 38 per cent within the Svalbard breeding inhabitants of this species from winter 2020-21.
