Scottish Crossbill (Loxia scotica)
Spotted Flycatcher (Muscicapa striata)
Only in the UK. Similar to Red and Parrot Crossbill in plumage. Bill size possibly the only visual identification clue, but even this overlaps with the other two species. Bill is usually deeper and heavier than Red Crossbill. Certain separation from Parrot Crossbill in the field by visual characters alone, probably not possible. Species status mainly upheld by isolated breeding population and differences in excitement calls from other crossbills. Calls probably play an important role in maintaining the reproduction barrier between Crossbill populations with different bill-size. See Birdlife link below for more info.
Sound:Calls very similar to Parrot Crossbill, and sonogram analysis may be needed for certain identification. Flight and excitement calls show most unique quality. Sonogram image above by Ron Summers (used with permission). A detailed article about crossbill calls can be found here.

Largest flycatcher in covered area. Easily overlooked bird with greyish brown upperparts and pale underparts. Crown and chest speckled. Bill and legs black. Slim white fringes to flight feathers and greater coverts. Body, wings and bill longer than in Pied Flycatcher, leaving a more elongated impression. Erect posture. Behaviour similar to congeners, with rapid darts and frequent hovering when hunting insects. Flicks tail and wings while perched.
Sound:The discreet calls often goes unnoticed. Most calls high pitched with a buzzing, "electric" timbre. Alarm call a sharp, drawn "tzreeeee-check", with the second syllable abruptly clipping the sound. Song a primitive, slow series of various buzzing and very high pitched sounds. No recurring phrases.
