Radisson - 2014 / Smiley & Princess
birdcamfan:
TPC, Thanks, that's what I call an in-depth description. You're attention to detail could teach our news media a few lessons!

Okay, here's what I have observed.
When the birds are on the chicks, Smiley has his left wing tip over his right. Princess is just the opposite, right over left.
Princess hunkers down while on the nest, Smiley is more upright, sort of like an on guard pose.
When you can see them face on, Smiley's malar stripes appear squared off and rectangular while Princess's are more rounded.
The Peregrine Chick:
There a few ways to tell Princess from Smiley (other than her personality), not always fool-proof depending on light, location & how their feathers are sitting ... however, here are a couple of things to look for if you are so inclined ...
* Princess is still larger than Smiley though definitely harder to tell because he is larger than Ivy was
* Overall colouration - he's darker than she is overall - she's always had lighter-coloured markings on her head and she's older and her feathers are more light slate-grey than dark slate-grey
* Head patterns - Smiley's head is uniformly dark, no markings though sometimes you can see the lighter-coloured under-feathers all peregrines have. Princess has her crown which this year is more roughed-up, less crown-like - with their back to you you can see their heads usually.
* Breast patterns - Princess has speckles higher up on her breast which granted is hard to see when she's on the eggs/chicks, so look up the sides of her breast by her wings - you can usually spot speckles high up the sides - Smiley doesn't have those.
* Facial pattern - often you can spot a white band across the "bridge" of Smiley's beak, Princess' isn't as evident unless the light is right; they both have decently sized and irregularly shaped cheek patches, problem is facial feathers move around as the birds move so unless there is something very distinctive - like T-Rex's full black cap or Princess' crown, feathers patterns are a tricky thing to use for identification
* Leg bands - unless you can read the numbers, the bands won't help you much they both have black/green bands on their left legs and anodized purple bands on their right legs. And when they are in the nestbox, they tend to stay low so hard to see their feet
Anyone else have other distinguishing characteristics to share?
