Bird call classifiers

Decision table for identifying bird calls
Features Melody Pitch Speed Mnemonic Name Description Audio
einfach rhythmisch low (1-3 KHz) slow Dreizehenspecht - Trommeln Behavior: Seine unauffälligen Rufe sind nicht laut und tönen ähnlich wie jene des Buntspechts. [Portrait]
einfach rhythmisch medium (1-5 KHz) slow Pirol 3 somewhat harsh ascending notes, more melodic than a Eurasian jay call
einfach rhythmisch medium (1-5 KHz) slow Amsel - Alarmruf Loud falling series of notes, unlike anything else you hear from a blackbird
einfach rhythmisch low-high (1-7 KHz) fast Kohlmeise Chuck-a-chuck-a-chuck, sometimes preceded by higher 'wheat!'
einfach rhythmisch high (3-9 KHz) slow Tannenmeise Analyze stuff at XC vs my BirdNet 962 - several notes, not sure if all coal tit as BirdNet suggested. XC has two-note high-low alarm call but simple song-like calls too
einfach rhythmisch high (3-9 KHz) slow Grauspecht In the FOK course, Christina said he sounds like he's running out of gas, which is a great description.
einfach rhythmisch high (3-9 KHz) slow Blaumeise Low-high-high, with lightly raspy start, rather high. Christina compares it to a tennis ball - that might be a different call?
einfach rhythmisch high (3-9 KHz) fast Kleinspecht Vogelwarte wie oben..hohe Rufreihen
stereotypisch melodisch high (4-7 KHz) slow Grauschnäpper General: To me something between a one-note and an extremely simple melody, namely med-med chk-hi-med-med, with a very irregular speed, not at all like a metronome.
Call: Most calls high pitched with a buzzing, "electric" timbre. [Link]

stereotypisch melodisch low-high (2-8 KHz) fast Stieglitz Der Name 'Stieglitz' ahmt den Ruf (sti-ge-lit) angeblich nach. [Link]
einnotig low (2-3 KHz) fast Kleiber Schnelle Sequenz - ist es der oben erwaehnte 'twit'?
einnotig high (4-7 KHz) slow Wasseramsel Chirp repeated 1-2s.
einnotig high (5-7 KHz) slow Gartenbaumläufer General: See the sonogram how the song may descend rapidly from 7Khz to and then climb from 5 to 5.75 KHz, a kind of reversed checkmark. However I find it hard to distinguish from a single note. I'm not a bird ;-(
Call: calls with a loud (Wikipedia says shrill) “tyt tyt” [Link]

einnotig low-high (1-8 KHz) slow Buntspecht General: A chirping (that I couldn't associate in my mind with a woodpecker), repeated at somewhat irregular intervals of about a second
Call: Nabu: Der häufigste Ruf ist ein kurzes und spitzes „kix“. Ist ein Buntspecht aufgebracht, etwa durch einen Artgenossen, kann man ein schnelles Schnarren hören. [Link]

einnotig high (7-9 KHz) slow Waldbaumläufer General: Fairly regularly spaced single tseep at 7-9KHz
Call: Contact call a drawn, high-pitched "tzreeee". Similar to Goldcrest in timbre, but of longer duration with a vibrating and slightly rolling tone. Generally repeated in evenly paced, slow series (unlike Goldcrest). [Link]
Raspel einnotig medium (1-5 KHz) slow Eichelhäher Typically harsh jay call. I would say a contact call usually means 'Here I am', answered by 'Good, here I am.' Listening to two jays in the Swiss mountains of Toggenburg, it sounded like 'HEY IDIOT, HERE I AM...WHERE THE HECK ARE YOU?' 'WHAT? YOU HAVEN'T FIGURE IT OUT? OF COURSE I'M OVER HERE. PEABRAIN.' On the other hand, anthropomorphism is always dangerous, usually completely wrong approach.
Raspel, absteigend einnotig medium (1-5 KHz) slow Grünfink Raspy descending note
Wiederholungen einnotig high (7-10 KHz) slow Singdrossel - Kontaktruf One or two high chirps followed by long pause of 1-2 seconds
stottern/kieseln einnotig low-high (2-7 KHz) slow Klappergrasmücke BirdID says: Warning call a hard "check" similar to Blackcap but slightly softer
stottern/kieseln einnotig high (3-8 KHz) slow Zaunkönig Sputtery/trilly repeated notes at 3-8 KHz
stottern/kieseln einnotig high (3-9 KHz) slow Mönchsgrasmücke General: Sputtery/stoney, but may have other calls too.
Call: The Blackcap may generate a perplexing variety of territorial calls, though the typical contact call is a hard, tongue-clicking "teck teck" which has a scolding quality to it. It's not dissimilar to the 'pebble-clacking' call of the Stonechat. [Suffex Wildlife Trust]
stottern/kieseln einnotig high (4-9 KHz) slow Rotkehlchen Personal: A single note usually repeated twice. Somewhat sputtery. BirdID refers to 'a thin, electric "tick". In one source said to be used as alarm call.
Call: A variety of calls is also made at any time of year, including a ticking note indicating anxiety or mild alarm. [Link]
absteigend einnotig high (5-7 KHz) fast Heckenbraunelle Swooping staccato call 0.5 seconds long heard near Lendikon. Repeated irregularly after 1-3.5 seconds.
absteigend einnotig high (6-9 KHz) slow Sumpfmeise Falling note, relatively long, sometimes repeated
aufsteigend einfach rhythmisch medium (2-4 KHz) slow Fitis - Kontaktruf Whoop very similar to chiffchaff, etc. but starts at an even level, then ascends.
aufsteigend einnotig medium (2-4 KHz) slow Zilpzalp Repeated rising note, not too loud
aufsteigend einnotig medium (2-5 KHz) slow Gartenrotschwanz - Kontaktruf At least in French, this is called the huit call. Not very consistent in tone from one note to another. Some stick to 3-4 or 3-4.5 KHz, others 2.5-5.5.
aufsteigend einnotig medium (3-5 KHz) slow Buchfink - Regenruf General: Repeated ascending note, faster than the long starling whoops, but compare with the black redstart. There are many different calls, the Marler book describes the 'chink' call as functioning as a mobbing and separation call. At XenoCanto I find calls described as "ping", "pik" (same thing?), "pchew", "duit", "huit", "ti-huit".
Call: Der sogenannte Regenruf der Männchen, „schrrüt“, der selbst in benachbarten Ortsteilen deutlich variieren kann, erklingt nur während der Brutzeit. Als Regenruf wird er bezeichnet, weil er kurz vor oder sogar während des Regens zu hören ist, wenn die anderen Vögel verstummen. [DasHaus]

aufsteigend einnotig medium (1-6 KHz) slow Star Das hoere ich ab und zu (und gern), der lange aufsteigende Pfeif von tief (1 1/2 KHz) bis hoch (6.5 KHz).
aufsteigend, stottern/kieseln einnotig medium (4-5 KHz) slow Hausrotschwanz XC560014 matches exactly waht BirdID describes: 'Alarm call is a chat-like alternation between short, high-pitched "wit" sounds, and series of hard and dry "teck".' The high-pitched call I heard recently was between 5 and 6 KHz, which could help to distinguish between other birds with a deeper voice. The whooping call is sometimes listed as an alarm call.
