Poland 15 – 23 May 2010
Birds
Spring brings strutting hordes of ruffs to the marshes together with dancing brigades of white-winged and black terns. Thrush nightingale, great reed warbler and white-spotted bluethroat arrive early and sing delightfully, often from exposed positions. Soon they are joined by scarlet rosefinch, red-breasted flycatcher, aquatic, river and barred warblers together with the fluting golden oriole. Raptors such as white-tailed eagle and Montagu’s harrier show frequently, while penduline tits bring extra delight by building much-admired nests.
Eight species of woodpecker are present in Białowieża foest, including black and white-backed. Their holes provide homes to flycatchers, starlings and pygmy owls. Other woodland birds include lesser spotted eagle, nutcracker and hazel hen; red-backed shrikes can be common in surrounding fields and meadows.
Mammals
As everywhere, mammals can be difficult to see, though in Biebrza and Białowieża the chance of sightings are quite good. Elks can usually be seen grazing or loping in the marsh. Wild boars may be surprisingly obvious; there are many hares, but no rabbits. Pine marten is possible, as are red squirrels. Tarpan or Konik horses, now frequent inhabitants of British nature reserves, are being bred to revive a species close to the original wild horse of Europe.
Other wildlife
Marsh, edible and green tree frogs join the fire-bellied and grey toads in suitable wetlands. Dragonflies are not numerous in May but include Siberian winter and white-legged damselflies. Among early butterflies, Camberwell beauty and large tortoiseshell are popular with British visitors.
Plants
Biebrza holds a multitude of water-loving plants such as water soldier, sundew, yellow marsh saxifrage and a range of marsh orchids. Trees are much admired in Białowieża with certain individuals famous for their size. On the woodland floor there are hepatica, anemones, lungwort, sweet woodruff and carpets of ransoms. A curious mix of northern, alpine and eastern species can include long-leaved speedwell, bastard balm, spiked rampion and, we hope, lady's slipper orchid.
