Bird call classifiers

Decision table for identifying bird calls
Features Melody Pitch Speed Mnemonic Name Description Audio
simple rhythmic low (1-3 KHz) slow Eurasian three-toed woodpecker - drumming Behavior: Seine unauffälligen Rufe sind nicht laut und tönen ähnlich wie jene des Buntspechts. [Portrait]
simple rhythmic medium (1-5 KHz) slow Eurasian golden oriole 3 somewhat harsh ascending notes, more melodic than a Eurasian jay call
simple rhythmic medium (1-5 KHz) slow Common blackbird - alarm call Loud falling series of notes, unlike anything else you hear from a blackbird
simple rhythmic low-high (1-7 KHz) fast Great tit Chuck-a-chuck-a-chuck, sometimes preceded by higher 'wheat!'
simple rhythmic high (3-9 KHz) slow Coal tit 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
simple rhythmic high (3-9 KHz) slow Grey-headed woodpecker In the FOK course, Christina said he sounds like he's running out of gas, which is a great description.
simple rhythmic high (3-9 KHz) slow Eurasian blue tit Low-high-high, with lightly raspy start, rather high. Christina compares it to a tennis ball - that might be a different call?
simple rhythmic high (3-9 KHz) fast Lesser spotted woodpecker Vogelwarte wie oben..hohe Rufreihen
stereotype melodic high (4-7 KHz) slow Spotted flycatcher 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]

stereotype melodic low-high (2-8 KHz) fast European goldfinch Wild melody (remember these birds are also kept as songbirds in cages. the German name Stieglitz imitates its call (sti-ge-lit) - though I don't hear that! [Link]
one note low (2-3 KHz) fast European nuthatch A long fast sequence of notes - is it the 'twit' call mentioned above?
one note high (4-7 KHz) slow White-throated dipper Chirp repeated 1-2s.
one note high (5-7 KHz) slow Short-toed treecreeper 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]

one note low-high (1-8 KHz) slow Great spotted woodpecker 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]

one note high (7-9 KHz) slow Eurasian treecreeper 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]
rasp one note medium (1-5 KHz) slow Eurasian jay 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.
rasp, swoop one note medium (1-5 KHz) slow European greenfinch Raspy descending note
repetitions one note high (7-10 KHz) slow Song thrush - contact call One or two high chirps followed by long pause of 1-2 seconds
sputter/pebble-clatter one note low-high (2-7 KHz) slow Lesser whitethroat BirdID says: Warning call a hard "check" similar to Blackcap but slightly softer
sputter/pebble-clatter one note high (3-8 KHz) slow Eurasian wren Sputtery/trilly repeated notes at 3-8 KHz
sputter/pebble-clatter one note high (3-9 KHz) slow Black cap warbler 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]
sputter/pebble-clatter one note high (4-9 KHz) slow European robin 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]
swoop one note high (5-7 KHz) fast Dunnock Swooping staccato call 0.5 seconds long heard near Lendikon. Repeated irregularly after 1-3.5 seconds.
swoop one note high (6-9 KHz) slow Marsh tit Falling note, relatively long, sometimes repeated
whoop simple rhythmic medium (2-4 KHz) slow Willow warbler - contact call Whoop very similar to chiffchaff, etc. but starts at an even level, then ascends.
whoop one note medium (2-4 KHz) slow Common chiffchaff Repeated rising note, not too loud
whoop one note medium (2-5 KHz) slow Common redstart - contact call 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.
whoop one note medium (3-5 KHz) slow Common chaffinch - rain call 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]

whoop one note medium (1-6 KHz) slow Common starling I hear this occasionally and really enjoy it - a long rising 'whoop', as I call it', starting low at 1 1/2 KHz and rising to 6 1/2 KHz!
whoop, sputter/pebble-clatter one note medium (4-5 KHz) slow Black redstart 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.
