What colour is bird blood?

Specifically, the colour of the blood of the following birds:




Bonus points if you tell me WHY their blood is that colour.

Here's the explanation. I'm writing a story where the protagonist is a bird creature. Qess (that's the name of the protag) is injured, and I want to know what colour their blood is so I can accurately describe the colour.

    All birds have red blood. It's red because haemoglobin contains iron compounds, which forms the chemical bonds that allow blood cells to attach oxygen molecules and transport them around the body. Some critters use copper compounds for the same purpose, and their blood is blue. But copper compounds are not nearly as efficient as iron compounds for that purpose, so is not suited for highly active organisms like birds and mammals whose muscles and braincells have a massive appetite for oxygen

    Red. All blood with the iron-based haemoglobin is red.

    You'd better pick an Octopus if you want blue blood from the haemocyanin.

    Insects have Green or Yellow though.

    It's red because it has the same oxygen carrying protein called hemoglobin that mammalian blood does. It contains iron which it what the oxygen binds to. Oxygenated blood is bright red, oxygen depleted blood is much darker.

    Birds’ blood, like mammals, is red. Also like mammals, birds’ blood is a darker red before it hits the surface and exposure to oxygen, where then it turns a bright red, and it dries a darker, brick red.
