The last time a yellow-cheeked teal was seen in Sweden was in 2013 in Västmanland, by Lake Frövisjön.
Now it has been observed in Sweden again - this time in Uppsala near Fyrishov.
- The first observation was made on Saturday.
It is incredibly beautiful and very spectacular, says Jan Wärnbäck, chairman of the association Upplands birdwatchers.
"Hope it's wild"
There is uncertainty as to whether it is actually a bird from the wild or an escapee from a zoo.
- I hope it is wild but dare not guess.
In any case, it was not marked with any rings and the age indicates that it was not from a zoo, says Jan Wärnbäck, who himself was on site to observe the bird.
He is not alone in that.
- People from surrounding counties have come here to see the bird so it is definitely a thing, says Wärnbäck.
The rare bird was captured in a picture by Bo Söderström.

May originate in Siberia
The Rarity Committee has received several reports about the bird in Uppsala.
Now they must assess the observations and then categorize the find depending on whether it is concluded that it is a free bird or not.
- It is not certain that it can be decided.
But it is not at all impossible that it has its origins in Siberia, says Aron Edman, head of the rarity committee.
