The Iberian chiffchaff (Phylloscopus ibericus) is a species of passerine belonging to the family Phylloscopidae, the leaf warblers. This species is found as a breeding bird in southwestern Europe and northwestern Africa. It winters in western Africa south of the Sahara Desert.
However, when the holotype of P. c. brehmi was re-examined it was found to actually be an example of common chiffchaff which rendered Homeyer's name invalid. As of 2016, it is recognised as a separate species under the name Phylloscopus ibericus
The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific ibericus is Latin for "Iberian". The name "chiffchaff" is onomatopoeic, referring to the repetitive chiff-chaff song... Wikipedia →

Rare
Under 5% of wildlife watchers report an Iberian Chiffchaff sighting in Porto on a given day, based on 62 verified sightings from GBIF citizen-science data. It is the 109th most-seen of the 175 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report an Iberian Chiffchaff in Porto on a given day, against under 5% in October to August, the lowest months. That is one of Porto's driest months, with about 50 mm of rain against 140 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Iberian Chiffchaff sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 cities where we can rate Iberian Chiffchaff sightings, Porto ranks 4th at under 5%. The best odds are in Ouagadougou (Burkina Faso, about 20%), Lisbon (Portugal, under 5%) and Marrakesh (Morocco, under 5%).
Same genus: Phylloscopus
The closest relatives of the Iberian Chiffchaff that you can see in Porto (genus Phylloscopus, Leaf Warblers) are Common Chiffchaff (about 30%) and Pallas's Leaf-Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Iberian Chiffchaff is recorded against all the birds logged in Porto (62 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
