F2 backcrossed Brewster's Warbler hybrid

Super shot Warren. Impressive knowledge and dedication.

If I am understanding it correctly, without too much research, is a hybrid crossing with one of its parents or genetically similar individual of the parent produces the F1 and then a further cross to either the parent or genetically similar individual to the parent produces an F2. (I've picked up Covid -19 yesterday so am a bit fuzzy headed amongst other things...nasty, nasty bug).

Without you and your fellow Warblers input, I would never have picked up this knowledge. It's like a free biology lesson in wildcraft skills. Thanks for that.

That and they don't seem very selective with breeding, as long as they do breed...LOL.

a well taken in his own environment and I like the umbrella leave above it's head to this image, good one WARREN.

Thank you for sharing this beautiful image (along with all the others I've had the pleasure to view) Warren.  On top of that, you have shared fascinating background info on these wonderful birds!  A real treat to view - and learn, at the same time.

First, and foremost please get better soon !!! 

As far as your question, the way I understand it, to get to the F2 Brewster Warbler, a pure Blue Wing and a pure Golden Wing have to mate and that creates the first generation Brewster's. If the first generation Brewster's then mates with a pure Golden Wing, that creates the F2 backcrossed Brewster's as seen in the image I posted. I'm still not sure if the first generation Brewster's backcrosses and mates with a pure Blue Wing what the resulting characteristics of the bird are.  I need to do some more genomic research on that.  There are MANY variables to this as many of these birds have interbred in the past which leads to other various characteristics.  Most F1 Brewster's have some yellow wash on their underside, which my included image does not, which definitely makes him an F2.

I've done just enough genetic research with these Warblers to be dangerous, lol, as I am still limited in my knowledge but know just enough to know what I am pursuing to photograph.  However, I am confident that my included image is accurate as presented.  Hope this helps.

Again David,I'm sure I speak for all of us, hoping you feel much better soon !!!!

Thanks Warren.  Am mighty impressed with your knowledge.  Incredible.  That Covid-19 is just plain nasty. (am keeping an eye on Blood Oxygen levels, and alternating snoozing through the day.... have to surface every now and then... Yesterday had to keep an eye on the England cricket team who were in danger of actually winning a test. They did actually win after a glorious period of coming 2nd every match...  ..  

Cheers.

I am a Buffalo Bills fan. I feel your pain, David.  Hopefully this is their year as well !!

Beautiful image. This is the Hybrid I have pictures of.

Beautiful image of a very interesting bird. The markings are quite pretty. It's cool that we've got access to this sort of genetic information, to understand better these hybrid individuals.

Interesting-looking Warbler hybrid, thanks for sharing and the explanation, Warren.

Regardless of the genetic biology ( I am not an expert by any means, but I believe from what I have read, that your info is correct ), this is an excellent photo of certainly a very uncommon Warbler sub-species, Warren.
