Feeder Log: live results
Everything on this page is computed from submitted observations at the moment you load it. No cache, no hand-editing, and every table carries the sample size it was built from.
Tables are withheld until a section has at least 20 observations, and individual rows until they have 5. A number computed from three submissions is not a finding, and publishing it as one is how a research page turns into the same guesswork as everything else. Sections still filling say so plainly.
Most recorded species#
Not enough data yet. This section needs about 20 observations before the numbers mean anything, and there are 0. A ranked feeder-bird list built from observations rather than from other people's lists. Add an observation and it will appear here.
What each food brings in#
One row per food, counting only foods with at least 5 observations behind them. The column that matters is distinct species: it is the direct measure of reach.
Not enough data yet. This section needs about 20 observations before the numbers mean anything, and there are 0. Once it fills, this is the table that says which food actually pulls the widest range of birds. Add an observation and it will appear here.
What each feeder type brings in#
Our coverage analysis of the trait matrix predicts that platforms reach far more species than tubes. This table is the observational test of that prediction, and it is free to contradict it.
Not enough data yet. This section needs about 20 observations before the numbers mean anything, and there are 0. This is the live check on the trait-matrix result that platforms out-reach tubes. Add an observation and it will appear here.
Baffles against squirrels#
Submissions that recorded a definite yes or no on whether squirrels reached the seed, grouped by what was fitted. See the baffle defeat protocol for the controlled version of this question.
Not enough data yet. This section needs about 20 observations before the numbers mean anything, and there are 0. The point of this one is to put a real number on how often a baffle actually holds. Add an observation and it will appear here.
How long a new feeder takes to be found#
Not enough data yet. This section needs about 5 observations before the numbers mean anything, and there are 0. This replaces the usual vague "a few days to three weeks" with a distribution. Add an observation and it will appear here.
By region#
Not enough data yet. This section needs about 20 observations before the numbers mean anything, and there are 0. Regional splits are where feeder advice most often goes wrong. Add an observation and it will appear here.
