I've heard many comments about fewer Ruby-throated Hummingbirds in CT, this season. Is there a way to investigate this? Even a very unscientific comparison of total eBird sightings in 2026 vs. 2025 might be interesting, but I don't know how to make that query. Steve Mayo Guilford

E-Bird provides a set of state-level summaries that can be accessed here: https://www.birds.cornell.edu/home/us-state-level-conservation-data-summaries/#state-data. However, they only summarize data from 2012-2022. I took a look at the data for Ruby-Throated Hummingbirds in CT, and over that ten-year period, there was about a 15% increase in their population/number of reports in the state. However, that does not address whether something has changed this year. E-Bird also allows people to request access to a complete data set including checklists (more information on that here: https://science.ebird.org/en/use-ebird-data/download-ebird-data-products), so I've requested access. Maybe someone else already has access to the dataset and can give a better answer, but I wanted to share that e-bird does have resources for accessing their data, and also the increase in hummingbirds over the 2012-2022 period! Anecdotally, I felt that I am seeing more of them this year in SE CT, so I'm wondering if our experiences may be location-dependent. Looking at this map ( https://science.ebird.org/en/status-and-trends/species/rthhum/abundance-map?week=1), Ruby-Throated Hummingbirds are more abundant east of 91, and the positive trend in their abundance is more pronounced in some areas than others. If they end up giving me access to the full data set, I'll try to take a quick look to compare hummingbird reports over the last three years in different areas of the state, because now you've got me curious!

Here in Goshen, they were decidedly late arriving on spring migration. While that was by about a week, on average, numbers became normal in early May.
