Lucy's warbler (Leiothlypis luciae) is a small New World warbler found in North America. This species ranges includes southwestern United States and northwestern Mexico. It is one of only two warblers to nest in cavities.
Lucy's warbler is the smallest species of New World warbler. It measures from 9 to 12 cm (3.5 to 4.7 in) in length and can weigh from 5.1 to 7.9 g (0.18 to 0.28 oz), thus being slightly smaller even than the warblers formerly placed in the genus Parula. Among standard measurements, the wing chord is 49 to 61 mm (1.9 to 2.4 in), the tail is 33 to 41 mm (1.3 to 1.6 in), the bill is 7.8 to 9 mm (0.31 to 0.35 in) and the tarsus is 15 to 17.5 mm (0.59 to 0.69 in).
It is rather undistinguished compared to other wood-warblers, being perhaps the palest species in its family. Its head and upperparts are pale gray, while the underparts are whitish. It has a white eyering and a small, pointed bill. Both genders have a rufous rump, a diagnostic field mark. Adult males also have a small rusty patch on their crown. Juveniles are paler, with a tawny rump and buffy wingbars.
Lucy's warbler is closely related to Virginia's warbler, Nashville warbler and Colima warbler... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lucy's Warbler sighting in Guadalajara on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the 87th most-seen of the 184 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Lucy's Warbler in Guadalajara on a given day, against under 5% in March to October, the lowest months. That is one of Guadalajara's driest months, with about 5 mm of rain against 210 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Lucy's Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 7
Of the 7 cities where we can rate Lucy's Warbler sightings, Guadalajara ranks 3rd at under 5%. The best odds are in Phoenix (United States, about 10%) and Mesa (United States, about 10%).
Same genus: Leiothlypis
The closest relatives of the Lucy's Warbler that you can see in Guadalajara (genus Leiothlypis, Leiothlypis Warblers) are Nashville Warbler (about 30%) and Orange-crowned Warbler (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lucy's Warbler is recorded against all the birds logged in Guadalajara (49 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.
