All the Coal Tits were juveniles and aged as such by the moult contrast in the greater coverts. Coal Tits are unusual in that the adult type Greater coverts are actually shorter than the juvenile ones as can be seen in the photo below. The newer adult type are the inner darker ones and this bird has retained the outer 4 browner juvenile greater coverts.
The garden feeders aren't particularity busy as the weathers so mild a lot of birds are still foraging for natural food. the finches are enjoying the sunflower hearts though & I'm continuing to catch small numbers of Gold finches and Greenfinches. Some of the juvenile Goldfinches have a very limited post juvenile moult and retain quite a few old greater coverts such as this bird below. Note the brown tipped juvenile greater coverts.
Another interesting bird was this Greenfinch that seemed to have undergone an asymmetric moult with primaries 6-8 being new and secondaries 1 & 2 also seemingly replaced.
A good little session culminating in this Bronze Shieldbug - a new species for the garden!
