this time a few people began to experiment crossing British finches. The resulting birds, including siskin × goldfinch and even such beauties as crossbill × Eurasian bullfinch also remain to this day, often winning prizes at prestigious shows. The breeding of such hybrids can, however be notoriously difficult. When writing about hybrid pairs, the cock always comes first, e.g. greenfinch × goldfinch is a greenfinch cock over a goldfinch hen.
