DEFRA says the risk of avian flu spreading to other UK wild birds is high.
The outbreaks involved different strains, including H5N6, H5N1, and H5N8.
The agency says there's still no evidence H7N9 has gained capacity for sustained spread.
H5N8 has now been confirmed in 40 countries, and South Korean scientists shared genetic findings from a recent H5N6 isolate.
So far there's no sign that H7N9 epidemiology is changing for humans, but for poultry, the virus has become more deadly.
Analyses of samples from China and Taiwan hint at resistance to antiviral drugs.
The 61 new infections reported last week push the mainland's total to at least 419 cases.
The 111 cases reported in the first half of January have already topped December's total.
In some hard-hit areas, sampling of poultry environments in December showed increased virus levels compared with that time in past waves.
The fast pace of newly reported illnesses during China's 5th wave of illness has already topped last season's total.
