• Dear Sir, I am interested in finding papers about hybrids between Serinus serinus and Serinus canaria. Are these crosses fertile in F1 and next generations? Data in literature seem to be somewhat conflicting. I got the paper written (in year 1968) by my colleague from Institute of Ecology of Polish Academy of Sciences. Prof. Zimka wrote in this publication that crosses between Canary asnd European Serin (F1 generation) had not properly developed testes and ovaries. There was also feminization or masculinization in hybrids. He meant birds one year old. He told me later that older males 2 years old can be partly fertile but it was not published.. Prof. Zimka passed away few years ago... Thanking in advance, Truly yours, Maciej
