Each season brings a different experience at our nature reserves. In spring, the air is filled with birdsong as they compete to establish territories and attract a mate. In summer, look out for young birds making their first venture into the outside world. Autumn brings large movements of migrating birds - some heading south to a warmer climate, others seeking refuge in the UK from the cold Arctic winter. In winter, look out for large flocks of birds gathering to feed, or flying at dusk to form large roosts to keep warm.
On spring evenings, long-tailed ducks can be seen displaying in their breeding plumage. Hear skylarks displaying.
See a variety of nesting waders including oystercatchers, lapwing, curlew, snipe and redshanks. Tufted ducks, teals and mallards also breed on the loch. Arctic terns, Arctic skuas, kittiwakes and great skuas often use the loch for bathing. Otters are present on the reserve, but you are more likely to see droppings or spraints than the otters themselves.
Loch of Spiggie becomes one of Shetland's most important lochs for wildfowl, especially whooper swans that are returning from their breeding grounds. Other passage and wintering wildfowl include greylag geese, tufted ducks, pochards, goldeneyes, wigeons, long-tailed ducks and teals.
The wildfowl are still present in large numbers, especially whooper swans and winter ducks.
