1cy michahellis with 2cy (presumed) cachinnans

such dark chocolate birds with already worn coverts and tertials and with fairly much white interspersed (especially in the still juvenile scapulars) are readily recognizable michahellis. the other bird is the presumed cachinnans discussed in 1627.

uncertain 2cy

without seeing more detail i'd leave such individuals unidentified but i have a strong inclination towards cachinnans here. quite a messy pattern...

adult female with short bill and 2cy cachinnans

this adult female cachi is remarkably short billed! p8-10 old (with p8 being exposed), renewed p not visible.
the 2cy has some interesting scaps with largely brown centers and dentated pale margins. patterns like this i predominately associate with 2cy summer michahellis, not cachinnans like in this case. this bird is more in focus (pattern better visible) in the overview pic 1624.

adult male cachinnans with bright bare parts and thayeri-pattern

unusually bright (yellow) bill base and legs for a late summer caspian gull. usually legs are grey or pinkish and bill base is ebony/colourless at this time of year. probably a hormonal thing. note also thayeri-pattern in this individual: mirror and tongue melt into each other at least in p10 (probably in p9 also). longest renewed (not fully grown) primary is p6. iris medium pigmented.

ad cachi, 1cy and adult micha

f.l.t.r.:
adult cachinnans with old p10,
1cy michahellis (sleeping)
and the same adult michahellis as in pic 1621. now p10 mirror is well visible, but apparently lacking a p9 mirror.

uncertain 1cy

my gut feeling says michahellis for this bird. mostly because of bill shape, smudge around eye (not only shadow) and waved scapular fringes. GC pattern unclear, TT pattern cachoid well but possible in micha.

ad micha standing, with large moult gap, 3cy cachi

if fully adult or subadult - hard to tell since no p9 mirror visible. i see the old primaries as p8-p10, thus with p8 being exposed. moult gap must be large since there isn't even p5 tip visible!
micha characters: square head with very pale iris, bill with bulbous gonys and 'swollen' also on upper mandible. striation concentrated around eye. strong and very yellow legs for mid august, no p9 mirror.

the other two birds are a 3cy cachinnans with much black in bill and a 1cy cach/mich (discussed in the next pic, nr. 1621)

mix of cachi and micha

from left to right:
1cy micha with womewhat cachoid GC pattern and narrow subterminal band to 2nd generation scaps
3cy cachi "openbill" (prob. irregularly grown mandibles) with broken TT pattern. p1-p7 renewed, p8 shed, p9(?) and 10 old.
3cy cachi, discussed in pic 1618
2cy micha(?) discussed in pic 1616

3cy cachinnans, 2cy michahellis

immaturity signs: brownish centered lesser coverts, brown hue to newly replaced MC and GC, bill colour, head striation. TT not with solid dark center but diffuse brownish. all the old primaries are shed, longest new 3rd generation primary is p7.

the other bird is a presumed 2cy michahellis (discussed in pic 1616)

2cy michahellis

with this high and blunt tipped bill, pale eyes and bold contrasting pattern this should be a 2cy YLG.

1cy, 2cy and adult cachinnans, uncertainties

apart from the adult on the left i'm not 100% sure on any of the other 3 birds.
2nd from left might be a 1cy michahellis, already worn and with justa few scaps replaced.
then this 2cy bird which i think is a cachinnans, of the contrastingly patterned "zebra" type. distal part of bill is bulbous, so not so typical caspian...
the rightmost bird shows a combination that drives me creazy: upright stance with high breast bend, flat belly and bump behind legs suggests cachinnans (which it probably is!) but note that many michas on the beach looked extremely similar in this respect, especially concerning the upright stance. covert fringes are narrow and not undulated, GC and TT pattern are better for cachi as well. but then we have this exposed fresh replaced scapular with a bold double anchor pattern which usually strongly points towards YLG!

1cy + 2cy micha (2)

diffuse pattern (which could very similar or even identic in 2cy cachinnans). p7 is longest fully grown 2nd. generation primary, p8 and 9 missing, p10 old juvenile. with its upright stance it could cause confusion but note bill and head shape. eye looks small and placed forward in the head. bill base largely pale. could this be a strange male cachinnans with a bill shaped like in michahellis?

the 1cy is m.o.l. typical.
the 2cy has a diffuse pattern (which could very similar or even identic in 2cy cachinnans). p7 is longest fully grown 2nd. generation primary, p8 and 9 missing, p10 old juvenile. with its upright stance it could cause confusion but note its bill in the next pic.

difficult runt 2cy, probably cachinnans

i have seen runt ind. of this "type" in winter which i called michahellis at that time.
now this looks much more like a cachinnans but nothing is really typical...

comparison of 2cy august cachinnans (left) and michahellis (right) (1)

2cy cachi (left) with long neck, smaller head, slimmer bill with pointed tip, no stark head-striation, small eye and mostly longitudinal dark markings in scaps.
2cy micha (right) with higher bill, strongly curved upper mandible at tip, square shaped, large and boldly striated head with large eyes, thick neck, lower scaps with irregular/dentated markings. this kind of pattern is usually typical for michahellis, it's also a bit colder dark brown in tone.
the only untypical feature in both is bill colour: black in the cachi and bicoloured in the micha while "it should be" the opposite.

2cy cachi with contrasting pattern, pale iris in 1st summer cachinnans

all coverts with very contrasting pattern, similar to michahellis.
2nd gen TT with the classic dark center and the large pale tip with narrow darksubterminal band. pattern on lower scaps longitudinal (sort of diamond shaped).
bill and body structure favouring cachinnans.
such a pale iris is not common in 1st summer cachinnans (hybrid?)

p6 almost fully grown, p7 very short (just black tip visible), p8-10 old (2nd generation), p10 with mirrors. no replaced secondary, yet.
2nd generation rectrices with rel. narrow solid black band but dense and fine barring towards base.

1cy cachi, scap with double-anchor

ondulated white margins on the lower rear juvenile scaps and quite a bold double anchor in the well visible renewed 2nd gen. scap, both not typical for cachi. however, GC and TT pattern are classic.

three difficult 1cy, cachoid michahellis

especially the one in the middle should be a micha with that bill. but its GC pattern looks more like that of a cachinnans. i don't want to put a name on the other 2 ind.
they can be either, in my opinion. look at their weird tertial pattern.
