Not really. Sometimes they start breeding in late December in parts of Cornwall. I did see a photo of spawn somewhere in the south about a week ago.
Haven't seen any yet in my pond. My first vary from late Feb to mid- March. Certainly mild enough. Suspect first wet night will see arrivals. Lovely photo- hope they have lots of success. I only get a fraction of the frogs I used too + suspect the Smooth Newts greatly reduce recruitment of new frogs to the population.
