Long-Tailed Skuas

It is not only the owls which are breeding well during the current peak in small mammal numbers. Long-Tailed Skuas are also cashing in on the abundant lemmings. These seem to have peaked in numbers during winter, but the numbers are still high enough for the birds to rear their chicks.

The are high numbers of grey-sided voles in northern Scandinavia at the moment and consequently the owls are breeding well, rearing large broods of chicks on the abundant food supply. Yesterday I saw Hawk Owls with a large brood, today I saw a brood of seven Short-Eared Owls.

 Short-Eared Owls have beautiful big yellow eyes

Owl chicks are of different ages, by a day or so between each. This is because the female begins to incubate as soon as the first egg is laid. In a brood of seven there is a large range of ages and sizes of the chicks. In this nest there were only four chicks still in the nest. The other three had wondered into the nearby shrubbery, which all helps to ensure that if the nest is brood are attacked by a predator, at least some chicks should survive.

It was raining for a couple of days here in North Norway, so we went for a drive down to Finland for a walk in the pinewoods. The birds were a bit quiet due to the rain, it was only a light drizzle, but it was good to see and hear Waxwings, Redstarts and Pied Flycatchers. And it especially good to come across a pair of Siberian Jays, and a fledged brood of Hawk Owls. There were at least five large fledglings, and the adults were unconcerned about us as they brought in voles, grey-sided, while we were there.

Lapland flowers

Arctic Bell-Heather Casiope tetragona

While looking for birds in north Norway, I find myself walking past some wonderful displays of wild flowers. Here are just a very few selected species. The bell-heather and diapensia grow up on the high plateux, where it is windswept and the plants all grow very low to the ground.

 
Diapensia lapponica

In the lower heaths and bogs one of the mose abundant plants is the Labrador Tea, along with various species of heaths, such as Mountain Heath Phyllodoce caerulea and Bog Rosemary Andromeda polifolia.

Waders in north Norway

 Spotted redshank

I am up in north Norway at the moment studying high latitude breeding waders. The habitats are lakeside mires within which there are several sub-habitats utilised by various waders for feeding and nest sites. Open water is used by red-necked phalaropes, open sedge is used by broad-billed sandpiper, close growing sedge is used by jack snipe, wood sandpiper and reeves. Spotted redshanks nest on the nearby heath and lead their chicks into the bogs to feed.
