How to best see the Peregrines

Morning,

I was wondering if anyone had any tips on seeing the elusive peregrines at Rainham?

I constantly see the blog/recent sightings full of peregrines, especially around christmas where you had six apparently? Turned up the next day and didnt see one!

Im really not an expert, or even close, so I probably just miss them. I know they tend to favour the pylons and I know the basics facts such as how they hunt and what not but any specific tips for seeing them at Rainham?
