Umeälvens delta is a large delta in Northern Bottenviken. It holds valuable coastal meadows, large deciduous forests, large fields and valuable wetlands.
At the Umeälvens delta 295 bird species have been recorded. The delta holds a few rarer wintering birds like: Pic tridactyle, Durbec des sapins, Bec-croisé bifascié, Pic cendré, and Sizerin blanchâtre. During each spring around 6000 Cygne chanteur stay at the delta. Around one thousand Canard colvert, Sarcelle d'hiver, and Canard siffleur use the area as feeding grounds during the spring. Also hundreds of Canard pilet, Garrot à oeil d'or, Harle bièvre and Fuligule morillon. Ducks who are rarely seen in Northern Sweden like Sarcelle d'été, Tadorne de Belon, Canard chipeau, Fuligule milouin, and Fuligule milouinan can often be seen.
Large amounts of wader use the delta as feeding grounds. Most common are Combattant varié, Bécasseau variable, Pluvier doré, Courlis cendré, Vanneau huppé and Chevalier sylvain. Also rare waders like Petit Gravelot, Phalarope à bec étroit, Barge à queue noire, Pluvier guignard, Barge rousse and Bécasseau falcinelle. Bruant rustique is regularly seen. Busard des roseaux and Bruant ortolan breed.
During spring the fields close to the delta are fillled with geese, passerine birds and waders. Some of the rarer birds often seen are Bruant lapon, Linotte mélodieuse, Pipit à gorge rousse and Tourterelle turque. During atumn the coastal meadows are once again filled with wading birds migrationg south. During autumn more arctic waders are seen, while less of the southern species are seen.
In several places in the nature reserve there are bird towers and other facilities for bird watching. See the map below. Click on a P in the map to get directions to that point. To protect nesting birds, you are not allowed to walk off marked trails between April 1 and August 15. Ramps, bird towers, hides and platforms may be used during this time.
A suspension bridge suitable for both wheelchair users and strollers makes Stora Tuvan accessible from the parking lot (see the map). On the island, an accessible ramp through lush deciduous forest goes out to the bird tower. The ramp is also available for the visually impaired. There is a hide at the far end of the headland.
