The line curves upwards at the EDGES for Leadens and downwards at the
EDGES for Satins - not always obvious, but this one is. A good way to
remember (very childish, but it works): Leadens Laugh (ie upwards
curving = a smile), Satins Sad (ie downward curving = a frown) - this is
my own invention, by the way, although I can't discount convergent thoughts!

The Leaden Flycatcher is one of the most misidentified birds in eastern
Australia, particularly in Queensland. Pic #365004 shows how a male
Leaden can appear against the light and easily mistaken for a Satin
Flycatcher, a species rarely seen in Queensland. One of the reasons they
are so often misidentified undoubtedly stems from the illustrations in
the field guides. Both painting and printing a blackish bird with a blue
sheen is no easy task so most of the illustrations are less than ideal,
but the main problem is that they fail to show correctly the main field
mark for males - the shape of the breast band. They all get it wrong -
only HANZAB shows it correctly. Look at my Satin Flycatcher pictures
#s366213D and 366214D to see the two compared - the demarcation line is
convex in one and concave in the other - chalk and cheese. Another
useful clue for birds seen from below is that Leaden Flycatcher males
have a grey undertail with clear white feather shafts - male Satin
Flycatchers have a plain, dark brown undertail in which the feather
shafts are not noticeable.
Females are another matter. Leaden females have a plain leaden-grey
crown whereas Satins have a bluish sheen (see pics #s365215 and 366205)
Some Satin females are a bit darker on the breast but this is a variable
character. Immatures are virtually indistinguishable.
Another reason confusion occurs is that some people are unaware of the
habitat preferences of the two species. Leadens occur in a wide variety
of habitats including mangroves. Breeding Satin Flycatchers are cool
country birds and except for far southern Victoria and Tasmania, are
only found at higher elevations. Nevertheless, both species are seasonal
migrants and can occur virtually anywhere in the brief periods they are
on the move, usually in March and September. In southern latitudes
Leadens usually arrive in September and the same territories are
re-occupied year after year whereas in northern Australia they are
regarded as sedentary. In the mountains near Canberra, I used to watch
both Leaden and Satin Flycatchers in adjoining territories, but this is
not common.
