Editor's note: "Hidden World of Birds in City" is about exploring a world of birds that usually goes unnoticed in urban spaces. This episode features photographs from Wang Xiaobo, who has been bird-watching near his residential community in Beijing for the past eight years.

Remember that little grebe who tried to chase away a common teal from its territory earlier in April? Now looks like it has got some good news as Wang found two new faces following the grebe for a evening stroll yesterday. This is the forth time that Wang has witnessed the success of little grebes nesting and breeding in the lake of his community since he started paying attention to birds. Based on previous records, little grebes usually arrive late March and leave in October. The try of the bird's. Last year's attempt failed. 

The little grebe family is not the only one who bears good news, the kingfisher couple are still staying, which also means the family-raising project continues; a Chinese blackbird chick has already been seen up and around out of the nest; as for the Eurasian hoopoe, the current focus still falls on searching for food to feed the young, which signals a positive message that chicks are under good care.
