Slightly out of focus but rather typical in appearance for a collybita subspecies. The yellow-brownish cast is obvious to the eyebrow and sides of breast. The structural expression as the bird looks in picture 1 is spot on for the species. Willow Warbler would look more elongated. Here the primary projection looks pretty long for a Chiffchaff, but is emphasized too much by the strong angle. Very common migrant in autumn. |

Subspecies: possible tristis Motorvejsbroen. This bird showed up when I was provoking with the alarm call of Plumbeous Vireo (very effective). This bird was also present where the tristis, 4203, showed up. I didn't pay attention to it as such in the field, but seeing the photos now it certainly looks rather green- and yellowless why it could be another candidate for a tristis...? |

Subspecies: tristis Ottehøjevej x Granatvej. [SIBERIAN] Afternoon and quiet overcast weather. Compared to the other bird this day, 4203, this one was calling spontaneously, and gave very good looks. It's probably a coincidence but I've never seen a normal Chiffchaff behave with such confidence. It foraged down to 1 meter from me and perched several times in the open, constantly giving its characteristic 'chicken-call'...Winner Winner Chicken Dinner..! 5 minutes later it continued through the vegetation. Also seen by Knud Boysen. Update 2024: Many birds mid April were calling with somewhat similar calls, but all turned out to be abietinus, the northern subspecies. The spectrogram revealed that they were not tristis. I did not make a spectrogram control with this bird in 2022, but today I ran it and luckily it appears a green go for tristis here, with the descending call being in the hertz frequency below 5 kHz. |

Subspecies: tristis Motorvejsbroen. [SIBERIAN] This bird showed up when I was provoking with the alarm call of Plumbeous Vireo (very effective). I first saw the very pale and well-marked eyebrow, giving hope that it was one of the rare species. But then I saw the rest of the bird, and knew that it was probably not. But it still looked different from the usual phylloscopus birds we see on Amager. The brown coloration and the beige colored strong eyebrow indicated this, and I ended up concluding that it was probably a Siberian Chiffchaff. There were other chiffchaffs present and they looked more like they use to. And they called normally. This bird didn't say anything, but when I tried to play the call and song of tristis it responded eagerly by moving fast from one spot to the other. I know you normally have to hear the birds before you can claim a tristis, by I feel confident above this and count it. |

Subspecies: abietinus? Pumpehus-broen og langs materielgården. Bird 3. Third bird suspected to be a Siberian chiffchaff -tristis. The sharp call made me suspect that. But spectrograms deviated constantly from a classic tristis, and after some research I'm now pretty sure all of these sharp-calling birds that we see during these days are of the northern subspecies. Perhaps the birds come from the eastern part of the range, close to where tristis belong, since there is a slight similarity to the quality of the call the two between. |

Subspecies: abietinus? Thicket between Ottehøjevej and Ellevehøjvej-sporet. Originally suspected to be a tristis. Both recordings of this bird. Bird 2. All observations of tristis without sound documentation are by default invalidated by the DOFbase Police. So I went out today again to get recordings. This bird and the one near Hejresøen were still in place. To the un-trained ear, like mine, I had the sound to be spot on for tristis, but when studying the matter closer it becomes clear that the call of tristis is more mellow and falling more at the end. Also the frequency interval for tristis is lower, mostly in the range of 4.5 to 5 Khz, whereas all of these abienitus calls range from 3 to between 5+ Khz. The behavior of these birds seem to be quite different from our birds, at least when it comes to vocalization. All the birds I have been following have been very persistent calling eagerly for long spells at a time, and without interacting with other phylloscopus warblers. They all seemed to have found their own little spot where they forage in between many other phylloscopus warblers. I suspect them to be waiting for better weather before migrating further north - it's been cold and wet for some days now, making it understandable why a small passerine prefers to stay put where there is good shelter and food. Notice how the visual presentation of the call changes shape drastically when altering the time scale along the x-axis. |

Subspecies: abietinus? Pumpehus-broen og langs materielgården. Originally suspected to be a tristis. Bird 3. As with the other bird, 5788+5790, this one was also still present today, third day. Inverted u-spectrogram, 4-5+ Khz, and constantly calling with this call according to xenocanto goes well with abietinus. Tristis shows a spectrogram flatter at the beginning and falling toward the end, and lower hertz. Initially, listening to the calls in the field, however, I was not able to detect much difference, and I have to admit that I was surprised to see that my spectrograms show this u-shape, since I hear it as a flat linear sound. One might speculate whether these birds come from a part close to the tristis population in northern Siberia, the contact zone where voices during learning are influenced by different sound pools. |

Subspecies: abietinus? Pumpehus-broen, Hejresøen. Originally thought to be a tristis. Bird 3. Fourth day. Still calling exclusively with the same call, but today it included a few chatter notes (in first sound clip) similar to the ones often heard at the beginning of the chiffchaff song. But it never got into singing. Perhaps it is a female. And perhaps it is a young bird, because today it started to flutter its wings several times, as a begging juvenile would. However, I've seen especially magpies do the same now in spring, and one shouldn't think it had anything to do with food begging but rather a behavior related to breeding, pair matching. But the bird continues not to be interacting with other phylloscopuses, though many are present. I tried to provoke it with song of both collybita chiffchaffs and tristis, but no response. Actually when I tried with Iberian Chiffchaff it seemed to be more interested, but without going crazy. The call is somewhat similar to what the Iberian has, but comparing the spectrograms they are very different. Interestingly, in photos 1 and 2 a yellow alula and underwing coverts are seen, and I think I have read that it can be a crucial character for identifying tristis - which should not have any yellow - hence all good for abienitus. Notice: the first spectrogram shows a fraction with chatter and the call. |

Lille sø, Kalvebodhøj, Sydvestpynten. Came in to harass the abienitus chiffchaff that was calling, and still suspected to be a tristis at that point. It looks rather brown and big, but didn't say anything. But I guess it is likely also an abienitus with rather pale bill and legs. I only saw it like this with the rear part concealed. |

Subspecies: abietinus? Lille sø, Kalvebodhøj, Sydvestpynten. Originally suspected to be a tristis. Bird 4. Practically sounding like the other abienitus I have had these days, but the spectrogram shows a rather different call - almost a straight upward-going sound without a drop at the end. Given the rather broad frequency range I believe it to be just a variety of the call of this subspecies. I would like to think that the many birds with unusual calls this spring is the result of more stopover birds than usual - birds probably waiting for the weather to clear up. |

Subspecies: abietinus? Frieslandsskoven. Bird 6. Bird number 6 with the aberrant weee call that is not a tristis but certainly doesn't sound like normal chiffchaffs either. Still investigating. As with the other birds it was calling spontaneously with this call, and only used this call while I was there. It's a sharp, loud and lively call and the bird was foraging here and there, probably pushed a little by me trying to get decent recordings and photos. The photos are as shot, but sunny afternoon light might be a bit too warm compared to neutral colors, why it looks more yellow than it is. I think. Notice the rather pale legs. |

Subspecies: abietinus? Granatvej x Ottehøjevej. Originally thought to be a tristis. Bird 1. 9th day. Interesting or irritating as you please: Today I got a positive confirmation that this bird is calling with two different calls intermixed. The new call sounds more like the typical huit call, but in a willow warbler fashion with a non-rising beginning of the call rather than the chiffchaff type that is more rising, why it doesn't really make the mystery about these birds smaller. New call in 1: Between 1.5 and 4 sec. New call in 2: 6.5 sec, 9-11 sec, 20.5, 23.5 and 25.5 sec. Also 1: willow warbler, barnacle goose, ring-necked pheasant, airplane, graylag goose.

Pumpehus-broen. Or same spot as the one chiffchaff calling strangely. This one was simply singing like a common chiffchaff, but comparing it with same-bird-174 I can't really say the appearance is very different. It looks rather gray-beige without too much greenish-yellow in it. I think something is wrong with the right eye, though it did open it later on. |
