2cy cachi standing, same as 1567 and 1568
two 1cy michahellis standing
note the more simply GC pattern in the bird behind with only broad and contrasting white margins. but the same bird has a typical micha bill tip, dark eye mask and very typical scaps with a bold double anchor.
the micha in the foreground is the same as in pic 1594 and to the right of it the same cachinnans.
comparison: left = 1cy michahellis, right = 1cy cachinnans
both fairly typical individuals. note the more contrasting and waved pattern in the micha and the overall plainer cachi with more white in inner GC and wider tertials crescents.
1cy cachinnans standing
in such birds there's nothing really "reliable" (note not so typical tertial, scap and GC pattern) - nevertheless the whole bird "screams" cachinnans to my eyes, especially when seeing its structure. this is merely a thing of jizz then.
2cy cachi with contrasting covert pattern (same as 1581 and 1582)
1cy cachi with thick and shortish bill (2), same as 1590
1cy cachi with thick and shortish bill (1)
2cy cachi with an odd bill
note apparently paler getting iris which is unusual for cachinnans at this age. however, structure and pattern indicate caspian gull, imo.
ad cachinnans standing
1cy cachinnans standing (same as 1586)
1cy cachinnans standing (same as 1587)
typical 1cy cachinnans, standing
adult male cachinnans, typical underwing pattern
same as in pic 1583 (left, head not visible)
p10 tongue and mirror very typical for this species with a rel. nearrow black median band on inner web, tongue ending rectangular, its borders being a bit shaggy/zigzagging.
group of both species on bread, 1cy micha with cachi call
- two adult cachinnans, moult gap at p7 in the left hand bird, a male type (see pic 1584), and a female type running, with palish iris.
- two 2cy cachis (partially hidden)
- eight 1cy, most of which are michahellis.
not sure on the identity of the bird to the right with the pale underwing.
the one with 2-3 median bands on outer rectrices, central right, with raised wings, is a michahellis.
it became really scary when i saw how the central left 1cy michahellis (an obvious one!) open its bill to call just like a typical cachinnans (nasal sound). it seemed not to be the only micha uttering cachi-like sounds!
difficult 2nd cycle, probably cachinnans, with contrasting pattern and bulbous bill (also in pic 1581 and 1591)
note different appearance of bill shape in these pics - to me it looks much better now for a male type cachinnans! note especially in the right hand pic the "classic" high bend on neck, flatish breast and long tibias! so - most probably a 2cy male "pontic" gull.
difficult 2nd cycle, probably cachinnans, with contrasting pattern and bulbous bill (also in pic 1582 and 1591)
not so easy bird as on first view it looks like a michahellis with its bulbous bill tip, strong curve of upper mandible, contrasting covert pattern and a lot of streaking concentrated around eye. note however in this and the following pic (1582) how different bill shape appears, that legs are long and skinny (for a male type bird!), note also the grey scaps with black along the shaft and the peculiar pattern of MCs: with a long pale distal part. and remember that especially 2cy spring/summer cachis can show a very contrasting "zebra" pattern.
its neck is swollen because it just swallowed a piece of bread
adult cachinnans showing wingtip pattern
moult stage: p8-p10 old, p7 shed, p6 still growing, p1-p5 fully grown renewed. palish iris, 'colourless' legs. note 'pencil streak' striation on head sides, crown and side of neck.
in the foregorund two 1cy michas, in the background a 2cy cachi and to the right a 1cy cachi.
some 1cy (cachi and micha) flying, pale underwings...
not all michas have dark marked underwings: note the second from left (right under the micha with bread) with remarkably whitish axilliaries and underwing coverts: it is a michahelllis!
apart from the other michas there's also a strikingly pale cachinnans just taking flight in the lower right.
some youngsters on bread (both sp.)
on ground: cachi (with bread), micha behind and a 2cy cachi to the right of them. in the air two michas, the one in the center being one i'll show in the micha-section as it has an unusually strong marked tail.
two 1cy cachinnans
both have the typical thumbnail-like pale tertial crescents, both look structurally good for pontic gull. but note the strong gc pattern in the left hand bird and the remarkable gonys in the right one.
