(last update: March 12, 2012)

Mew Gull heinei BLB E133621 13cy, 22 March 1997, Malmö, Sweden.

Figure 34: E133621 (381/97,2) 12-year old male (13CY), probable heinei. 22 March 1997. Originally ringed on 15 February 1986 in Belgium as winter visitor.

Fig 32 shows a nine-year old canus female hatched in Malmö. Note the rather pale grey upperpart tone and poor defined contrast between white and grey on primaries (compare with fig 28 and fig 34 below). Fig 33 shows another canus, a ten-year old bird hatched on Kandalasha, SW Kola peninsula. It is very similar to the female from Malmö depicted in fig 32. Fig 34 (below) shows a twelve-year old male, probably heinei, which was ringed as one-year old winter visitor in Belgium.
