Grey-headed woodpecker / Grauspecht (Picus canus)

Also known as: Grey-faced woodpecker, Gray-headed woodpecker

Vogelwarte Grauspecht. Note that it's quite green despite its name.
Classification: Genus Picus; Family Woodpeckers (Picidae)
Behavior:

Der Grauspecht gehört mit dem Grünspecht zu den «Erdspechten», die ihre Nahrung vorwiegend auf dem Boden suchen. Obwohl er fast so gross ist wie der Grünspecht, ist der heimlicher lebende Grauspecht ungleich schwieriger zu lokalisieren. Am ehesten verrät er sich durch die fallende, etwas melancholisch wirkende Rufreihe. Über seine Lebensweise ist vergleichsweise wenig bekannt. [Link]
Song:

Deutlich abfallende Tonreihe. 4-10 Töne. Absinken beginnt gewöhnlich erst mit dem dritten oder vierten Ton und wird etwas langsamer. Klingt etwas klagend (moll). Vor allem gegen den Schluss. Kann nachgepfiffen werden. (beim Grünspecht nicht ) [Link]

Da es selten zu sehen ist, habe ich wenig beschrieben.
Habitat:

The White-backed Woodpecker is the largest and rarest of the black and white woodpeckers. Since a few years only, individual breeding pairs have been observed in the east of Switzerland. Because of its special habitat requirements – natural forests with a great number of dying and dead trees – the occurrence of the White-backed Woodpecker is limited to remote and inaccessible forests. It has secretive habits and is most likely observed during the courtship period. [Link]

endangered Looking for it in Kaltbrunnenriet - didn't find it in June 2022.
Etymology:

Ihren Namen [Spötter] tragen sie, weil sie in ihren Gesang den anderer Vögel nachahmend aufnehmen („spotten“). [Link]
Yellow belly, brown back, very similar to melodious warbler. Sometimes has the punky ruffled head feathers.
Appearance and identification: Ebird: Distinctive features include longish, daggerlike bill, long primary projection in the wings, and square tail. Told from similar Melodious Warbler by usually conspicuous pale wing panel, longer wings, and marginally shorter bill. Usually difficult to see when singing except during song flights, when long wings are apparent. Found in tall forest with oaks and birch, mixed forest, gardens, and parks. [Link]
Geography:

Es gibt nur 100-150 Paare in der Schweiz, darum steht es auf der Rote Liste CH as stark gefährdet - und ist sicher schwierig zu finden. [Link]
Song:

Sein lauter, lebhafter und variabler Gesang setzt sich aus flötenden, zwitschernden und nasalen Tönen sowie Imitationen anderer Vogelarten wie Drosseln, Meisen, Schwalben oder Pirol zusammen. [Scheint mir aus Segmente von ~2 Sekunden zu bestehen.] [Link]

Song very virtuous and varied. Most similar to Marsh Warbler, but timbre and attack harder and more powerful. Tempo varied with many pauses, but includes longer, and more flowing sequences than Marsh Warbler. Song frequently interrupted by characteristic, nasal, high-pitched squeaks unlike Marsh Warbler. Master of mimicry. Imitations are often repeated several times before changing to melodious motifs or more "noisy" phrases. [Link]

General:

The corn crake, corncrake or landrail (Crex crex) is a bird in the rail family. It breeds in Europe and Asia as far east as western China, and migrates to Africa for the Northern Hemisphere's winter. It is a medium-sized crake with buff- or grey-streaked brownish-black upperparts, chestnut markings on the wings, and blue-grey underparts with rust-coloured and white bars on the flanks and undertail. The strong bill is flesh-toned, the iris is pale brown, and the legs and feet are pale grey. Juveniles are similar in plumage to adults, and downy chicks are black, as with all rails. There are no subspecies, although individuals from the east of the breeding range tend to be slightly paler than their western counterparts. The male's call is a loud krek krek, from which the scientific name is derived. The corn crake is larger than its closest relative, the African crake, which shares its wintering range; that species is also darker-plumaged, and has a plainer face. [more]

Bearded vulture / Bartgeier (Gypaetus barbatus)

Also known as: Lämmergeier

Wikipedia: Bearded vulture
Classification: Genus Gypaetus; Subfamily True hawks (Accipitrinae); Family Accipitridae
General:

The bearded vulture (Gypaetus barbatus), also known as the lammergeier and ossifrage, is a bird of prey and the only member of the genus Gypaetus. This bird is also identified as Huma bird or Homa bird in Iran and north west Asia. Traditionally considered an Old World vulture, it actually forms a minor lineage of Accipitridae together with the Egyptian vulture (Neophron percnopterus), its closest living relative. It is not much more closely related to the Old World vultures proper than to, for example, hawks, and differs from the former by its feathered neck. Although dissimilar, the Egyptian and bearded vulture each have a lozenge-shaped tail—unusual among birds of prey. [more]
Calls:

Display call a thin whistling with several register breaks, reminiscent of Honey Buzzard (Pernis apivorus). A passerine-like trill is also sometimes heard, but generally not a vocal bird. [Link]
