Mayr wrote about this event, "It was as if someone had given me the key to heaven."

'', which completed the evolutionary synthesis started by Darwin.
After Mayr was appointed at the American Museum of Natural History, he influenced American ornithological research by mentoring young birdwatchers. Mayr was surprised at the differences between American and German birding societies. He noted that the German society was "far more scientific, far more interested in life histories and breeding bird species, as well as in reports on recent literature."
[Barrow, Mark V. (1998), ''A Passion for Birds: American Ornithology after Audubon''. Princeton University Press. .]
Mayr organized a monthly seminar under the auspices of the Linnean Society of New York. Under the influence of J.A. Allen, Frank Chapman, and Jonathan Dwight, the society concentrated on taxonomy and later became a clearing house for bird banding and sight records.
Mayr encouraged his Linnaean Society seminar participants to take up a specific research project of their own. Under Mayr's influence one of them, Joseph Hickey, went on to write ''A Guide to Birdwatching'' (1943). Hickey remembered later, "Mayr was our age and invited on all our field trips. The heckling of this German foreigner was tremendous, but he gave tit for tat, and any modern picture of Dr E. Mayr as a very formal person does not square with my memory of the 1930s. He held his own." A group of eight young birdwatchers from

There are several connections linking Ernst Mayr to this new species of ''Toxicocalamus'', which make him, and this snake, the ideal candidates for a patronym.

Summary of Darwin's theory
Darwin's theory of evolution is based on key fact
A fact is a datum about one or more aspects of a circumstance, which, if accepted as true and proven true, allows a logical conclusion to be reached on a true–false evaluation. Standard reference works are often used to check facts. Scient ...

s drawn from them, which Mayr summarised as follows:
:* Every species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ...
is fertile enough that if all offspring survived to reproduce, the population would grow (fact).
:* Despite periodic fluctuations, populations remain roughly the same size (fact).
:* Resources such as food are limited and are relatively stable over time (fact).
:* Struggle for survival ensues (inference).
:* Individuals in a population vary significantly from one another (fact).
:* Much of the variation is heritable
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic informa ...
(fact).
:* Individuals less suited to the environment are less likely to survive and less likely to reproduce; individuals more suited to the environment are more likely to survive and more likely to reproduce and leave their heritable traits to future generations, which produces the process of natural selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charle ...
(fact).
:* This slowly effected process results in populations changing to adapt to their environments, and ultimately, these variations accumulate over time to form new species (inference).
In relation to the publication of Darwin's ''Origins of Species'', Mayr identified philosophical implications of evolution:
:* Evolving world, not a static one.
:* Implausibility of creationism.
:* Refutation that the universe has purpose.
:* Defeating the justifications for a human-centric world.
:* Materialistic processes explain the impression of design.
:* Population thinking replaces essentialism
Essentialism is the view that objects have a set of attributes that are necessary to their identity. In early Western thought, Plato's idealism held that all things have such an "essence"—an "idea" or "form". In ''Categories'', Aristotle sim ...
