Species of the same genus (<em>Petroica<\/em>) are widespread and common in Australia as are the robins in New Zealand.<\/p>\n<p>The tomtit is one of our smallest forest birds, easily recognised by its predominantly black plumage contrasting with a small bar of white on the wings and a white breast patch.\u00a0 On some males the breast patch becomes quite yellow, particularly at its upper margin.\u00a0 A small white dot is sometimes visible at the base of the bill.\u00a0 Females and juveniles are duller.\u00a0 The tomtit is usually first detected by its strident song and then by its habit of perching boldly when singing.\u00a0 On forest margins and in low stature shrublands all of this is even more obvious.\u00a0 If you are trying to find tomtit it really is important to be familiar with its song &#8211; some good examples being available from this website.\u00a0\u00a0\u00a0\u00a0<a href=\"http:\/\/nzbirdsonline.org.nz\/species\/tomtit\" target=\"_blank\" rel=\"noopener\">http:\/\/nzbirdsonline.org.nz\/species\/tomtit<\/a>\u00a0\u00a0\u00a0 You may also find it helpful to remember this by verbalising the song with a little ditty &#8211; perhaps:\u00a0&#8221; tiddly tiddly tiddly tit\u00a0\u00a0 &#8221;<\/p>\n<p>Male SI tomtit showing a particulary yellow breast (note the white bill spot and white wing bar)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Female SI tomtit<\/p>\n<p>(photo Craig McKenzie &#8211; NZbirdsonline)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0(photo Steve Atwood NZbirdsonline)<\/p>\n<p>Tomtits, like all of the Petroica, feed on invertebrates &#8211; usually what they can catch on the ground or trunk surfaces.\u00a0 Their habit of perching with head cocked to one side while they search for a wriggling grub is characteristic.<\/p>\n<p>Tomtits nest in cavities in rotting trunks which seems to make them particularly vulnerable to predation by rodents.\u00a0 Their distribution reflects this with their gradual disappearance from habitats where predation in greatest.\u00a0 In many South Island forests they are now only found at the higher altitudes where this predation pressure is somewhat less.\u00a0 While there are occasional records from coastal forests in Abel Tasman these are unusual.\u00a0 In contrast this species is commonly encountered\u00a0at higher locations such as the upper Wainui, Moa Park, Evans Ridge and Harwoods Hole.<\/p>\n<p><picture><source srcset=\"https:\/\/www.janszoon.org\/wp-content\/uploads\/2015\/06\/news-ResizedImage600816-SI-tit.webp 600w,https:\/\/www.janszoon.org\/wp-content\/uploads\/2015\/06\/news-ResizedImage600816-SI-tit-221x300.webp 221w\" sizes=\"(max-width: 600px) 100vw, 600px\" type=\"image\/webp\"><img src=\"https:\/\/www.janszoon.org\/wp-content\/uploads\/2015\/06\/news-ResizedImage600816-SI-tit.jpg\" height=\"816\" width=\"600\" srcset=\"https:\/\/www.janszoon.org\/wp-content\/uploads\/2015\/06\/news-ResizedImage600816-SI-tit.jpg 600w, https:\/\/www.janszoon.org\/wp-content\/uploads\/2015\/06\/news-ResizedImage600816-SI-tit-221x300.jpg 221w\" sizes=\"(max-width: 600px) 100vw, 600px\" class=\"alignright wp-image-969 size-full sp-no-webp\" alt=\"\" decoding=\"async\"  > <\/picture><\/p>\n<p>Project Janszoon anticipates that if rats can continue to be controlled across a broad expanse of the park those tomtit that disperse downslope will survive and breed.\u00a0 A gradual expansion of their range can be expected.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The tomtit (Petroica macrocepha) is a small forest and scrub dwelling bird found only in New Zealand.
