Editing Spring peeper (section)

=== Brood size ===
Spring peepers breed in southern areas from October to March, depending on the local temperature. In northern areas, they breed between March and June, when the warm rains start. ''P. crucifer'' typically lays around 900 eggs per clutch, but up to 1000 are possible. Females will lay eggs singularly or in groups of two or three.<ref>{{Cite journal |last1=Baud |first1=Donald R. |last2=Beck |first2=Melvin L. |date=2005 |title=Interactive Effects of UV-B and Copper on Spring Peeper Tadpoles (Pseudacris Crucifer) |url=https://doi.org/10.1656/1528-7092(2005)004[0015:IEOUAC]2.0.CO;2 |journal=Southeastern Naturalist (Steuben, Me.) |volume=4 |issue=1 |pages=15–22 |doi=10.1656/1528-7092(2005)004[0015:IEOUAC]2.0.CO;2 |s2cid=83788323 |via=BioOne|url-access=subscription }}</ref> Egg clusters are hidden under vegetation or debris at the water base.<ref name="www.biokids.umich.edu">{{Cite web |title=BioKIDS – Kids' Inquiry of Diverse Species, ''Pseudacris crucifer'', Spring Peeper: INFORMATION |url=http://www.biokids.umich.edu/critters/Pseudacris_crucifer/ |access-date=2019-03-20 |website=www.biokids.umich.edu}} In very cold weather, they hibernate under logs and loose bark. Spring peepers often call day and night as long as the temperature is above freezing, but they are mostly heard and usually not seen because they hide in dense plants. They are especially easy to hear due to their extremely loud [[mating call]] which gives them the name "peeper", but it is often hard to pinpoint the source of the sound, especially when many are peeping at once. The peepers generally breed close to dusk and throughout the evening and early morning hours. Their calls can be heard from as far as one to two and a half miles, depending on their numbers.{{cite magazine |date=11 November 2010 |title=Spring Peeper |magazine=National Geographic |url=https://www.nationalgeographic.com/animals/amphibians/s/spring-peeper/ |language=en}}</ref>
