They may be found in small ponds or wetlands, but usually these are near rivers or streams. They breed in ponds and pools adjacent or connected to streams and rivers. <\/span><\/p>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 16px;\"><b>Habits<\/b> <\/span><\/p>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 16px;\">Pickerel frogs breed in spring (late April, May, and June). The males call is a deep snore. It is shorter and higher pitched than the northern leopard frog&#8217;s call and is usually not followed by a chuckle as in leopard frogs. They call from the shore or from underwater in shallow portions of the wetland. Females lay 2,000 to 3,000 eggs. The tadpoles transform in two or three months.<\/span><\/p>\n<figure id=\"attachment_375\" aria-describedby=\"caption-attachment-375\" style=\"width: 400px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-375\" src=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Jackson_County_Iowa_2.jpg\" alt=\"\" width=\"400\" height=\"303\" srcset=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Jackson_County_Iowa_2.jpg 634w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Jackson_County_Iowa_2-300x227.jpg 300w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Jackson_County_Iowa_2-198x150.jpg 198w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Jackson_County_Iowa_2-150x114.jpg 150w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><figcaption id=\"caption-attachment-375\" class=\"wp-caption-text\">A pickerel frog, <em>Lithobates palustris<\/em>, from Jackson County, Iowa.<\/figcaption><\/figure>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 16px;\">Pickerel frogs usually stay close to the water. Few move into wet terrestrial habitats. I have seen pickerel frogs away from streams in damp, forested uplands in Allamakee and Clayton counties. These are usually large adults that will not dehydrate as quickly as smaller specimens. They overwinter in streams or rivers or may migrate to shallow ponds, if close. Pickerel frogs apparently produce toxic skin secretions that are distasteful and harmful to predators. The toxin is reportedly fatal if it is absorbed through the skin as other frogs (even other pickerel frogs) have been killed when they were placed in a small container with pickerel frogs. <\/span><\/p>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 16px;\"><b>Food<\/b> <\/span><\/p>\n<p><span style=\"font-family: Arial,Helvetica,sans-serif; font-size: small;\"><span style=\"font-size: 16px;\">Pickerel frogs consume insects, earthworms, and other invertebrates.<\/span> <\/span><\/p>\n<figure id=\"attachment_376\" aria-describedby=\"caption-attachment-376\" style=\"width: 640px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/2015\/12\/Pickerel_frog_Clayton_County_Iowa_2.jpg\" rel=\"attachment wp-att-376\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-376 size-full\" src=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_2.jpg\" alt=\"\" width=\"640\" height=\"427\" srcset=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_2.jpg 640w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_2-300x200.jpg 300w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_2-225x150.jpg 225w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_2-150x100.jpg 150w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><\/a><figcaption id=\"caption-attachment-376\" class=\"wp-caption-text\">A pickerel frog, <em>Lithobates palustris<\/em>, showing yellowish coloration on groin and legs, from Clayton County, Iowa.<\/figcaption><\/figure>\n<figure id=\"attachment_377\" aria-describedby=\"caption-attachment-377\" style=\"width: 640px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/2015\/12\/Pickerel_frog_Clayton_County_Iowa_1.jpg\" rel=\"attachment wp-att-377\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-377 size-full\" src=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_1.jpg\" alt=\"\" width=\"640\" height=\"427\" srcset=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_1.jpg 640w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_1-300x200.jpg 300w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_1-225x150.jpg 225w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/Amphibians\/Frogs\/Pickerel_frog_Clayton_County_Iowa_1-150x100.jpg 150w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><\/a><figcaption id=\"caption-attachment-377\" class=\"wp-caption-text\">A pickerel frog, <em>Lithobates palustris<\/em>, from Clayton County, Iowa.<\/figcaption><\/figure>\n<figure id=\"attachment_1722\" aria-describedby=\"caption-attachment-1722\" style=\"width: 640px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1722\" src=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/2020\/12\/Pickerel_frog_Dubuque_County_Iowa.jpg\" alt=\"\" width=\"640\" height=\"480\" srcset=\"http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/2020\/12\/Pickerel_frog_Dubuque_County_Iowa.jpg 640w, http:\/\/www.herpnet.net\/Iowa-Herpetology\/wp-content\/uploads\/2020\/12\/Pickerel_frog_Dubuque_County_Iowa-300x225.jpg 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><figcaption id=\"caption-attachment-1722\" class=\"wp-caption-text\">A pickerel frog, <em>Lithobates palustris<\/em>, from Dubuque County, Iowa.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Pickerel Frog (Lithobates palustris) Alternate names: Rana palustris by Jeff LeClere Pickerel frogs, Lithobates palustris, calling.
