I use Nik Dfine2 as an add on to Elements 14 Dale.
Its really easy to use, just select strong noise from the drop down box and it aromatically creates you an adjustments layer. You can select brush size and opacity, I normally go for around 80%.
First use a small soft edge brush to stop bleed through to unwanted areas like up against the tree stump/bird, then finish with a large brush to cover more area.
TBH I've had the add on for quite awhile now and the NR is the only tool I've used, highly recommend it
