[The information below was obtained from the European Commission's
website on avian influenza at
<https://ec.europa.eu/food/animals/animal-diseases/control-measures/avian-influenza_en>:

"In 2018, outbreaks of HPAI of subtype H5N6 were confirmed in poultry
in the Netherlands and Germany and in captive birds in the Netherlands
and Sweden up to March. [...]

In wild birds, only the HPAI virus of subtype H5N6 has been identified
in several member states: Denmark, Finland, Sweden, the Netherlands,
Germany, Ireland, the Slovak Republic, and the UK. On [15 Aug 2018], a
last case was detected in a wild swan in Denmark. [...]

In mid-December 2017, the Netherlands detected HPAI of subtype H5N6 in
a poultry holding and in captive bird holdings. Based on the genetic
analysis of HPAI H5N6 viruses recently detected in Europe and Asia,
the EU Reference Laboratory for avian influenza concluded that the
European strains can be differentiated from those strains associated
with zoonotic infection in Asia. Furthermore, they do not carry any
virulence markers strongly associated with human infection risk. There
have been no reported human infections with this particular genetic
sub-lineage of H5N6. [...]

A detailed overview on the situation in member states and the adopted
measures is given in the chronology of events
(<https://ec.europa.eu/food/sites/food/files/animals/docs/ad_control-measures_hapai_chrono.pdf>)
and maps
<https://ec.europa.eu/food/sites/food/files/animals/docs/ad_control-measures_hapai_chrono_map.pdf>."

Since the event in Germany was detected in a flock of rare and
endangered breeds, this event was reported as highly pathogenic
influenza A viruses (infection with) (non-poultry including wild
birds). According to the OIE Terrestrial Code Chapter 10.4 on
Infection with Avian Influenza Viruses, Article 10.4.1 defines
"poultry" as "all domesticated birds, including backyard poultry, used
for the production of meat or eggs for consumption, for the production
of other commercial products, for restocking supplies of game, or for
breeding these categories of birds, as well as fighting cocks used for
any purpose. Birds that are kept in captivity for any reason other
than those reasons referred to in the preceding paragraph, including
those that are kept for shows, racing, exhibitions, competitions, or
breeding or selling these categories of birds as well as pet birds,
are not considered to be poultry"
