Garden Wildlife update

Here is how things stand with breeding birds in our garden:

• both House Sparrow nest boxes are occupied and we regularly see parties of up to eight adults around the garden and visiting the seed feeder.
• Blue Tits are nesting in the hole in the apple tree which they use every year.  They are frequently in and out and ignore me when I am working in the garden close by, so presumably they are feeding chicks.  There is another Blue Tit nest in the shrub border on the south side of the garden.
• Dunnocks are probably nesting in the dense honeysuckle on the other apple tree.  We have seen up to four adults, but now we rarely see more than one suggesting that birds are sitting on eggs.
• We have two Robins which are tolerating each other, but we have not seen any interaction between them so far.
• We have seen a male Blackbird gathering food close to the house and suspect that he may have a nest in the garden but do not know where.  We rarely see a female
• a male Chaffinch is singing loudly from a concealed location on the south side of the garden and may have a nest nearby, but maybe in a neighbour's garden. 
• Great Tits are frequent visitors, but I do not think that they are nesting in our garden. 
• A Chiffchaff is often heard calling just beyond the bottom fence, but does not seem to venture any closer.
