Breeding conditions:

Waders arrived earlier than to the coastal regions to the north. First records of Spotted Redshanks, Ruffs, and Broad-billed Sandpipers were made on 24 May, of Pacific Golden Plovers, Common Sandpipers, Pintail Snipes, Bar-tailed Godwits, Green Sandpiper - on 25 May, of Terek Sandpipers - on 29 May, of Common Snipes - on 31 May, of Wood Sandpipers, Grey-rumped Tattlers, and Red-necked Phalaropes - on 2 June. Voles and Wood Lemmings had high numbers, but wader reproduction was hardly successful, judging by very low numbers of these birds in August.
