Duck hunters in Otago can look forward to an above-average season this year if the weather plays it part.
This year’s mallard monitoring results were 10% above the average count since 2015, Otago Fish & Game officer Bruce Quirey said.
“Rivers and other permanent bodies of water are likely to offer the best shooting for mallards due to dry conditions, unless there is substantial rain before opening weekend on May 1,” Mr Quirey said.
Otago Fish & Game conducted an aerial survey last week across parts of the Taieri, Clutha and Pomahaka.
Mallard monitoring is a trend count and results can be affected by many variables, such as water levels and weather, on the day.
Some parts of Otago are very dry and there are variances between areas across the region.
River transects had more ducks on them this year than usual, Mr Quirey said.
“Parts of the Clutha and Pomahaka rivers had some of the highest recorded concentrations of ducks since 2015.
“One river section had almost double its previous highest count.”
Many permanent ponds had good mallard counts.
“One lucky pond had four times the highest number recorded on it in the past six years.”
On cross-country transects, mallard counts were well below the average. There is a lack of ephemeral water in shallow ponds and paddocks. Ducks have largely moved away from many of these areas.
A third of all ponds surveyed had no ducks. Several ponds were dry. However, a few of those ponds had not recorded mallards since counting began in 2015.
Farmers have reported large flocks of ducks on harvested grain in South Otago and West Otago. Fish & Game has had several calls from farmers about nuisance populations of ducks.
“If the weather conditions are right, hunters should be in for a good harvest.
“Hunters want low cloud, rain and some wind on opening weekend.”
The MetService is forecasting showers, rain and fine spells in the Clutha district during the next week. Central Otago is expecting rain and showers followed by fine weather.
There was no mallard monitoring last year because of the Covid-19 lockdown.
Otago’s paradise duck population is looking stable, based on this season’s counts.
An aerial count of paradise ducks in February found numbers similar to 2019 and slightly higher than 2020.
The highest counts were in Styx Basin, in the Maniototo, parts of the Ida Valley, Central Otago, and Lake Tuakitoto, in South Otago.
The paradise duck count is conducted in late summer while the birds are unable to fly due to moulting. Paradise ducks are likely to have dispersed to other locations since then.
