This bird was captured during a Photo Walk at the Arizona-Sonora Desert Museum. Believe me there was plenty of trash before getting this one. My camera has a small sensor so to maintain resolution I used On1 Perfect resize prior to cropping. This is a screen capture after on left

I'd be quite pleased with this, Peter. Very nice focus and detail on his head.

Hi Peter,
Very nice capture of a bird in flight. I know it's not easy most of the time.
But I am confused about what you mean by
As hopefully you are aware, resolution is defined as number of pixels per unit length (ppi = pixels per inch). I can have a 6000px x 6000px image set to 72ppi, 300ppi, 400ppi or whatever, and it will still be 6000px x 6000px in size so anyone saying 'maintaining resolution/ppi' doesn't make any sense to me. Pixel count is defined as just the total number of pixels in an image.
Resolution has meaning only when used for sizing images for printing. For web display, resolution is totally meaningless. For web display only pixel dimensions and hence total pixel count matter.
Also I am not sure you needed to resize the image for web display, unless the pixel dimensions of the original image are unusually tiny.
All browsers will scale down an image, if required, to make it fit into whatever space has been allocated to it by the CSS styling on a web page. My screen is 1920px wide. Consequently, my browser has scaled down your image to about 700px wide (~350px wide for each half).
If you did a 100% crop of the bird in the original image and if it was more than 700px wide then you wouldn't need to resize the image at all for web display. It would be better to publish the 100% crop.

Thank you Peter. Then unless you need to submit a print I assume they have specified pixel dimensions and/or pixel count minimums.
Good luck with your entry.
