Maple flowers

There are different types of Maple trees around the village. I am not sure exactly what they are all called. Maybe someone is good at tree identification and can put me right? The maples are in bloom this week. The flowers are bright yellow and stand out against the dark branches and the blue sky. The leaves burst out at almost the same time and are very thin and crinkled and unobtrusive for the moment. Together they crown the trees with a halo of gold. The example shown here can be seen in the Charlton Down Nature Reserve.
