With luck
About 10% of wildlife watchers report a Thick-billed Kingbird sighting in Cabo Pulmo National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 74th most-seen of the 100 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Thick-billed Kingbird in Cabo Pulmo National Park on a given day, against under 5% in December to June, the lowest months. That is one of Cabo Pulmo National Park's driest months, with about 15 mm of rain against 120 mm in September. July and August have too few records to rate.

GBIF citizen-science records
It is estimated from how often the Thick-billed Kingbird is recorded against all the birds logged in Cabo Pulmo National Park (8 verified sightings from 2019 to 2026), 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.
