Neither city can be declared the clear winner: historical surveys found that Berlin residents watched birds more often and fed them slightly more, while Seattle residents reported spending more on bird food and had a higher estimated aggregate economic value for common urban songbirds. Those results measure different behaviors and attitudes—not a single, direct measure of how much people like birds—and they do not establish which city’s residents are more interested today.
What did the Seattle–Berlin comparison find?
The answer depends on what “likes birds more” means. Berlin comes out ahead on reported bird-watching frequency and, modestly, on bird feeding. Seattle comes out ahead on recalled bird-food spending and on a modeled estimate of aggregate economic value. The researchers also found broadly similar numbers of bird-supporting activities in the two cities. Taken together, the evidence shows interest in both places, not a definitive ranking of residents’ affection.

The key comparison comes from research by Barbara Clucas, Sergey Rabotyagov and John M. Marzluff, including a 2014 study of urban songbirds and a related chapter on human–avian interactions in Berlin and Seattle. The studies used surveys, not direct observations of every resident’s behavior. Their results describe respondents in historical samples; they are not a current citywide poll.
| Measure | What the reported findings favor | What the measure can—and cannot—tell us |
|---|---|---|
| Watching or identifying birds | Berlin | Reported frequency of an activity, not intensity of affection. |
| Feeding birds | Berlin, slightly | Participation in one bird-supporting behavior; the pattern varied by age and urbanization. |
| Bird-food spending | Seattle | Recalled average expenditure, influenced by spending choices and economic context. |
| Conservation concern and membership | Mixed | Berlin respondents more often rated environmental or conservation issues highly; Seattle respondents more often belonged to a conservation organization. |
| Estimated aggregate economic value | Seattle | A city-level model combining spending and hypothetical willingness to pay—not an individual affection score. |
How often did residents watch or identify birds?
Berlin respondents reported watching or identifying birds more often than Seattle respondents in the chapter’s survey results. A majority in both cities said they did this daily, but the Berlin responses showed greater frequency overall. The reported city difference was statistically significant (χ²=19.37, df=5, p=0.002), according to the chapter on human–avian interactions in Berlin and Seattle.

This is the clearest direct result in favor of Berlin if the question is specifically, “Where did surveyed residents report watching or identifying birds more often?” It does not mean every Berliner watched birds more than every Seattleite, nor does it show that a person who watches more often necessarily feels greater affection. The survey asked about a behavior that can reflect opportunity, routine, attention, or interest.
It is also important not to turn a statistically significant historical difference into a claim about current residents. The chapter’s result is evidence about responses collected for the study, not a 2026 measurement or a guarantee that the same difference persists.
Did Berliners feed birds more often?
The chapter reports that Berlin residents fed birds slightly but significantly more than Seattle residents. That result points toward Berlin on this particular behavior, but the authors also found variation associated with urbanization and respondent age. It should not be read as a uniform difference applying to every neighborhood or age group.
Feeding is one way people support or engage with birds, but it is not a complete measure of bird interest. Someone may watch birds without providing food, or may feed birds as a routine without closely observing them. Survey responses about feeding therefore complement the watching result; they do not settle the broader question by themselves.

The 2014 study considered a wider range of bird-related activities, including noticing birds, providing food, offering nest boxes or plants, and other forms of support. Its authors reported similar numbers of bird-supporting activities across Seattle and Berlin overall. That broader finding is a useful check against overemphasizing one behavior: the cities had different patterns on individual measures, without a decisive overall activity winner.
Why was Seattle’s bird-food spending higher?
Seattle respondents recalled spending more per year on bird food on average. In the unweighted samples, the reported mean was US$49.17 in Seattle and US$11.26 in Berlin. With the study authors’ weighting, the corresponding figures were US$52.26 and US$11.37. The 2014 cross-continental economic valuation study also notes that more Berlin respondents purchased bird food, even though Seattle respondents spent more on average.

The share of respondents who buy bird food and the average amount spent are separate statistics. A city can have more buyers while its average reported expenditure is lower. Neither figure tells us directly how much affection residents feel: spending can reflect budgets, prices, purchasing habits, and the ways people choose to support wildlife. The amounts are recalled expenditures from survey responses, not a record of every purchase.
The figures are reported in U.S. dollars. They should be understood as the study’s historical expenditure estimates, not converted into a current purchasing-power comparison or treated as present-day prices. The study fieldwork took place in Berlin from August to December 2008 and in Seattle from October 2009 to February 2010.

What do conservation attitudes and membership suggest?
The results are mixed on these broader indicators. Berlin respondents more often rated environmental or conservation issues as very or most important: 80.0%, compared with 57.4% of Seattle respondents. Seattle respondents, however, more often reported belonging to a conservation organization: 17.7%, compared with 4.8% in Berlin.
These figures do not directly measure fondness for birds. A general rating of environmental issues can encompass many concerns beyond birds, while membership records one form of organized participation. They show why one proxy should not be substituted for the whole question: concern and organizational involvement point in different directions, and neither is a bird-affection score.
What does the economic-value estimate mean?
The study estimated a lower-bound aggregate economic value for common urban songbirds of about US$119.9 million per year in Seattle and US$70.3 million in Berlin. On the face of those modeled city totals, Seattle is higher. But the totals are not a comparison of the typical resident, and they cannot be interpreted as proof that an individual Seattle resident values birds more.
The authors’ estimates combine household-level bird-food spending with stated willingness to pay for public conservation measures, including hypothetical questions involving finches and corvids. They describe the aggregate figures as lower bounds. One part comes from recalled spending; another asks respondents what they would hypothetically pay. Both have limitations, and the city totals also depend on the household totals used in aggregation.

Aggregate dollars answer a different question from survey frequency. A large citywide total can reflect the number of households and the modeled inputs as well as individual responses. It is useful as an estimate of economic value under the study’s approach, but it is not a fair shortcut for ranking personal affection across two cities.

The 2014 study drew on 209 Seattle residents and 460 Berlin residents. Its fieldwork took place in Berlin from August through December 2008 and in Seattle from October 2009 through February 2010. Researchers surveyed residents across multiple neighborhoods and urbanization levels, asking about bird-related behaviors, attitudes, expenditure, and support for conservation.

The chapter and the 2014 paper provide related evidence, but their samples and measures are not identical for every reported finding. For example, the chapter’s watching-frequency result and feeding comparison should not be treated as though they were necessarily calculated from exactly the same respondents and survey instrument as every expenditure or economic-value figure in the paper. The findings are best read as complementary parts of a research picture, not collapsed into one composite score.
Survey answers also have ordinary limits: people may recall spending imperfectly, and reported behavior is not the same as observed behavior. The economic estimate adds another distinction because willingness to pay is hypothetical. These limits do not make the research useless; they define what its results can responsibly support.

So, who likes birds more?
If “likes birds more” means reporting more frequent bird watching or somewhat more bird feeding, the historical surveys favor Berlin. If it means higher recalled average spending on bird food or a larger modeled aggregate economic value, they favor Seattle. If it means overall affection, the available measures cannot identify a winner.
The most accurate conclusion is that both populations showed substantial engagement with urban birds, with different indicators pointing in different directions. The results are historical and do not establish which city’s residents are more interested now. No current representative survey directly comparing Seattle and Berlin residents’ bird attitudes is identified in the cited research.
For readers who want to connect with bird-related activity in Seattle today, Birds Connect Seattle’s community-science information describes ways to take part in local bird projects. That is a current participation resource, not evidence for a present-day comparison with Berlin.
Frequently Asked Questions
Did the researchers ask people directly whether they liked birds?
The research compared behaviors, attitudes, recalled spending and hypothetical willingness to pay rather than relying on one direct question that could rank affection. That is why the findings support a qualified comparison instead of a single definitive winner.
Does the Berlin result mean people across Germany watch more birds?
No. The comparison concerns survey respondents in Berlin and Seattle, not representative samples of Germany and the United States as a whole. It should not be generalized to either country.
Were all the bird-watching and spending figures collected from the same people?
Not necessarily. The chapter and 2014 paper report related findings, but their samples and measures are not identical for every result. Treat the findings as complementary evidence rather than as one combined survey score.

The reported aggregate estimate was built from particular survey-based inputs, including recalled household spending and hypothetical willingness-to-pay responses. It represents a modeled minimum under the authors’ approach, rather than a complete accounting of every way residents value birds.
