Miscellaneous Finnmark wildlife

Following on from the previous post, here is a selection of other wildlife bits and pieces that I photographed while wandering about Finnmark. This opening shot is a general one of the landscape. There is a mosaic of large and small lakes nestled in glaciated hollows. These lakes are fringed with various types of mire, or the basins can be entirely filled by mire. The lakes are used by diving ducks such as Tufted Duck and Goldeneye and the mires are used by breeding waders such as Wood Sandpiper, Reeve and Broad-billed Sandpiper. The hills and ridges are clothed with Birch woods and are typically used by breeding Willow Warblers, Red-spotted Bluethroats and Willow Grouse.

The Birches, Mountain Birch Betula pubescens ssp. tortuosa, are twisted and grow as if coppiced at the base. They are well spaced with dwarf birch and willow, and lichen-rich heath between.

Some of the birches have grown into marvellous shapes, and they must be very old. Perhaps it is hundreds of years since the seeds germinated.

There were lots of these Cranberry Fritillary Bolaria aquilonaris butterflies sunning themselves on the lichen covered gaps between the trees. Or I think that is what they are, if anyone knows better, please advise.

The butterfly's body was covered with long hairs, an adaptation to life in high northern forests, where it can be cold at any time of year.

Another butterfly that was flying at the same time was this Arctic Ringlet Erebia disa. Several of these were flitting over and landing on the mires, the type which was dominated by a carpet of sphagnum moss with abundant stems of Hare's Tail Cotton Grass Eriphorum vaginatum, a food plant for the larvae.

Another plant that grows in the woodland is Juniper Juniperus communis. These small trees are probably as old as the birches if not older, but not all those grey stems are juniper, there is a Greenshank Tringa nebularia sitting on its nest at the base of this one.

Down in the valleys there are hay meadows, and most have a rich yellow cast of buttercups. And some also have stands of Globeflower Trollus europaeus. They like the rich wet soils on the flat open fields.

And next to one field rich with Globeflower, I found a large stand of Tall Jacob's Ladder Polemonium acutiflorum, a stunning plant of wet rich soil, and typically found in old hay meadows in northen Scandinavia. It reminded me of Himalayan Blue Poppy.

Simple beauty.
