No. It is a white bird with purple coloring on its wings and tail.
Someone could say it looks purple from the outside but because it’s actually made up of different colors, they would be wrong in their answer to the question. That person is misinformed about this particular fact. The colors on this bird are due to recent markings over darker grey feathers which have now faded so that one can only see the outline; coupled with a white face, neck and chest, you get pink against brown under tones for an overall effect of purple-ish gray-ishness.
The use of violet or lavender should not be found to describe any shade of blue other than dark shades like periwinkle and lilac; light shades of blue are different colors entirely.
As for what’s up with this bird, it seems to be off its feed as it is sitting on the ground away from any known types of food. Maybe it’s tired after a long day of flying around to different places, but home is just where the heart is.
